Open source computer mouse by Ploopy
10mon 6h ago by lemmy.ca/u/lightrush in opensource@lemmy.ml from lemmy.ml
I needed another corded mouse and this time around I thought of PKL@mastodon.social and pronk@mastodon.social instead of Logitech's shareholders. These guys make open source mice among other open source hardware under the brand Ploopy. You can order one from them, assembled or as a kit, or you could print and build it entirely by yourself.
The mouse itself is pretty great. Coming from a long line of Logitech (MX518/G5/G500/G502), it's a bit larger than what I'm used to but I think I'm getting accustomed to it.
Here's another shot of it:
I've got to say "Ploopy" is one of the absolute worst names I've ever seen. Before I even saw the picture, I thought "I bet it looks like shit."
It's like an alien name out of Rick and Morty. 😂
Opensource projects often have terrible names.
Gimp, libreoffice, lemmy, Apache... just the ones that come to mind.
Gimp is a funny acronym that explains exactly what the software does. Libreoffice also tells you exactly what the product is. Lemmy is quick, catchy, easy to remember, and has a story behind it. Apache is... pretty bad.
Ploopy is literally "poopy" with an extra letter.
Gimp refers to sexual exploitation. Often the "exploited" is a willing participant but often not. Regardless it's "funny" the way a 12 year old finds drawing dicks on things funny.
Libreoffice only tells geeks exactly what the product is. My team, who uses Libreoffice, couldn't explain what Libre means, and no one can pronounce it.
Being quick and catchy is a pretty low bar. No one knows or cares about the story behind Lemmy. It sounds silly in conversation.
Gimp refers to sexual exploitation.
Like CBT and dozens of other terms, those damn psychologists and their Cock and Ball Torture.
Libreoffice only tells geeks exactly what the product is. My team, who uses Libreoffice, couldn't explain what Libre means, and no one can pronounce it.
Not sure if this is serious or not ?
If they're illiterate perhaps wider reading beyond Manga would help?
Gimp refers to sexual exploitation.
No, it doesn't.
Libreoffice only tells geeks exactly what the product is.
The target market is primarily geeks.
no one can pronounce it.
Sounds like your coworkers should expand their horizons. Libre is a common word in (at least) 2 widely spoken languages.
Being quick and catchy is a pretty low bar.
Not when you're naming a product. You think its hard to get people to use Lemmy, imagine trying to sell them on "Federated Link Aggregater Website."
It sounds silly in conversation.
As does Google, Instagram, and Tiktok but they at least managed to pick silly sounding names that don't sound like a child trying to describe a loose bowel movement.
Yeah, as opposed to weird shit like Apple, Google, Facebook, or earphones like the Sony Model EA-JX1000JT
Ploopy fills my hand really well
“I like resting my hand on my Ploopy”
It almost sounds like a vintage game sound, like “bleep bloop”, but worse, fecally worse.
I'm sorry but that's such a ploopy take. You can't just judge something by it's name 🙄
So I'm to take from this comment that your butt isn't a dream butt? Or like, despite the name, there's no relevance?
I'm plooping confused.
After reading up it sounds like a decent product but they should definitely consider rebranding.
I bought a Ploopy Thumb a few years ago. I assembled it myself, and was pleasantly surprised at how easy it was (when actually following the instructions).
The small button on the right has broken twice, which wasn't a problem because I just downloaded the stl file and reprinted the button assembly.
I wanted horizontal scrolling, so I used QMK to make the trackball a scroll wheel when the right side button is pressed (that may explain the faster button wear). It was surprisingly easy, and there was even a comment in the source code pointing out which line I should modify for horizontal scrolling support. I guess they expected people to want this feature.
The price is high, but I don't expect to buy another mouse unless my needs change. The open source hardware and software is excellent, making repairability 10/10. The edges of the buttons are slightly rough, but I have the 3d printing files, so I get to choose what material it's made of and what post processing / smoothing is used. It hasn't bothered me enough to do anything about it.
While I can't recommend a trackball mouse to anyone, I can recommend Ploopy. It's one of the few products that I feel like I actually own.
How do you use a trackball mouse? Does moving the mouse and moving the trackball both move the pointer? Or one moves the pointer and the other does something else?
The mouse stays in one location with grippy feet and the trackball moves the cursor. There is no sensor for mouse movement. It does take a while to get used to.
The reason I chose it was that I didn't have enough desk space to move a mouse. I barely even had enough space to put the mouse. Now that I've moved house, I just like the novelty. It's not as accurate as a regular mouse.
I would love a mouse that could do both regular movement and trackball movement so I could have 4 axis inputs. Sadly, I haven't found any like that.
It's not as accurate as a regular mouse.
This is not true of all trackballs. Some can be more accurate than a mouse with the push of a button.
That may be technically true, but what's stopping someone from using the same button on a regular mouse?
A regular mouse can have a large amount of movement with your elbow and very fine control with your wrist. Your thumb on a trackball may have more range or precision than either, but not both combined.
My personal experience is that a trackball mouse is a little less accurate when trying to move a large distance precisely. Perhaps I just need more practice.
Do you have a button in your regular mouse that enables precision mode?
I don't personally have a regular mouse, but most "gamer" mice have a DPI button.
I have seen several pro gamers use the DPI button on their mouse to rapidly change their precision while playing. I suspect it would take more practice than I'm willing to put in, but they seem to use it to great effect.
Ok.
I helped a user who exclusively uses a trackball and started getting used to it within seconds. My thumb was definitely not used to the trackball but I very quickly adapted and could navigate the computer normally
How'd you make the surface this smooth?
Overuse and poor lighting.
I know some people have used an acetone vapor bath with ABS prints. I've never looked into what works with PLA.
Just to save the heartache, acetone vapor does not work with pla.
LOL, makes sense. I'm considering using epoxy. Seems like there's a product that can be brushed on. It fills the gaps. Can be painted if desired.
I'd be interested to see how well it works.
I'll try to remember to post if I end up doing it.
What I really want is this, but with a trackpad instead of a trackball.
They do have a trackpad, but not in this shape.
I was surprised when I started using the Steamdeck. The Steamdeck's trackpad felt almost identical to my trackball mouse, and it took effectively no time to get used to it.
The advantage of a trackball over a trackpad is that you can spin the ball for high movement speed, then stop it after a set time for fairly accurate distance. A trackball (or trackpad) will never be as accurate as a regular moue, but it is surprisingly usable (after a few months or practice).
I've used several trackballs, but they have all been seriously uncomfortable for me and my specific brand of RSI. My current "mouse" is a Steam Controller, but using it one-handed isn't great due to the uneven weight distribution. I also have much better accuracy using a trackpad vs a trackball.
Ideally, I just want a Steam Controller cut in half with a more confortable grip that doesn't dig into my palm.
Those layer lines look like a perfect place for all sorts of shit to gather and stick to.
If one has sweaty hands - stay away from 3D-printed / soft plastic shell mice.
I couldn't agree more. I also hate when mice or keyboards can not be easily disassembled to be properly cleaned. In this case I guess it's a matter of printing precision and/or material (don't have my own printing experience, so maybe somebody else can comment on it)
Many people will say "just sand it down". But the extruder-printed plastic is still going to be porous as heck. A perfect place for germs.
Personally, I'd use the 3D model to create a negative mold of sorts, and then cast it out of something more human-friendly. But I haven't looked at the complexity of this model, this would have to be designed accordingly.
Your mold idea makes me wonder if cast aluminum could be practical for a shell for this.
How do you usually do that?
Do you create a negative of the model digitally or take a mold of the printed parts?
What kinds of human-friendly materials do you use? And do you need any special equipment for it?
The adult toys community would have some guides. You print the object, cast the mold around it and then fill the void with silicone afaik.
Is silicone rigid enough? Adult toys have slightly different requirements from many other 3D printed things.
Maybe you could vapour-smooth it.
Is it comfortable in the hand? The surface looks super rough
All Ploopy's stuff looks rough. I think they're 3D-printing them. Maybe one day they'll progress to something that gives a nicer result.
I was looking at their trackballs but the ambidextrous ones look awkwardly tiny and have rattly bearings, in addition to the rough finish. I support what they're doing but I wish the products were a bit less prototypey.
Yeah, definitely 3D printed.
It looks rough, but it's actually fairly comfortable.The only bit that bothered me was the edge of one of the buttons, and a nail file fixed that in seconds.
I think they're 3D-printing them. Maybe one day they'll progress to something that gives a nicer result
Yes they are 3D printed
Poorly 3D printed.
The layering issue could be solved by orienting the object at a 45° angle
I could reprint the housing one day, when I get a printer myself. 😂
The whole point is that it’s open source and they want people to be able to print them themselves.
Theoretically, you can mold it to fit your hand but the tolerances and mountings make that a hassle.
As for the print itself? Most people just do a quick print and have the telltale ridges from layers. But you can futz with settings to improve the smoothness or just finish the print itself. At which point it is not going to be as smooth as injection molding but it will be more "different" than "bad".
It depends how it was printed.
As a SUPER simplified basic: Any 3d print consists of walls/perimeters and infill. The walls are the exterior surfaces of the print. The infill is what is inside. And the vast majority of prints tend to be sparse infills. So rather than solid plastic beneath those walls, you mostly just have air and a mesh structure of some form.
So if the wall is thick enough (generally referred to as "number of walls")? Sure. If it isn't? You'll just see the void inside the shell itself and make things much worse.
What is generally done to reduce "3d printed texture" is a mixture of smaller print layers (so the ridges are much thinner), printing with more walls, and actually lightly melting the exterior surface (either through chemicals or heat).
VKB are probably the kings of the mid-range sicko HOTAS market and I am like 90% certain they 3d print the shell of their sticks for the Gladiator (?). But they do such a good job that I genuinely can't be certain. Whereas the vast majority of ploopy builds... aren't that.
Looks like a bitch to clean. Gonna get all sorts of grease collecting in those grooves…
It feels good. I'm thinking of smoothing it with epoxy but it's not necessary.
Only as good as your 3d printer and settings I'd say
Super cool and I totally see the appeal, but at nearly 3x the price of my Logitech g502 for a 3d printed mouse with a technically inferior sensor, it's a big ask.
Now do printers.
I have written a more detailed comment on it before, but 2d printing is much more technically complicated than 3D printing, and the resolution is literally an order of magnitude difference (0.2mm vs <42um) and the printer has to print full color on any surface with microdots in a very very short time. People would throw the printer out if it took 10 minutes for a single paper like a large first layer takes in 3D printing.
We were ok with dot matrix printers. We are and will be ok with black and white prints. Open Source community will be ok with a slow and ugly print. The company just need to allow their monopoly to be broken. I don't think they will.
I often wonder how difficult it would be to create an aftermarket control board for existing printers.
Yes please!
What is your experience with the scroll wheel? Some time ago I was interessted in a Ploopy but the non clicky scrollwheel put me off.
It's alright. It's not as nice as the flywheel/clickwheel on G502 but it's alright. It doesn't accidentally spin for me so far. I imagine one of the custom buttons could be used to enable/disable scrolling along with some script, if it becomes a problem.
My scroll wheel was very stiff and irritating at first. It did loosen over time and is now completely useable. It doesn't free-spin, but it also doesn't take a lot of force to move.
The lack of clicking is a little disconcerting, but not a deal-breaker for me. I guess you could add an extra part to make it click — like putting a playing card in the spokes of a bicycle wheel.
Because I bought the trackball mouse, I changed the trackball to scroll when a button is held. I now have horizontal and vertical scrolling, and don't use the scroll wheel except for middle clicking.
I have the same mouse, and that scroll wheel is unusable. It requires a ton of effort to just scroll tiny amounts because the sensitivity is waaay too low and it cannot be adjusted. The rest of the mouse is really nice because it runs QMK.
I set up drag scrolling as a workaround for the shitty scroll wheel, which allows you to press a button (or a combination of buttons) and then use the mouse's optical sensor as an omnidirectional scrolling device until you release the button.
I set that up on my Ploopy Adept hand trackball mouse as well. It's my favorite mouse I've ever used.
Layer lines, too expensive.
Looks less comfortable than one of those 10~15€ brandless mouses at MediaMarkt
Layer lines
You say "free hand grip for less strain" weird.
I've been using this mouse for almost a year now. No complaints.
3D printed stuff looks so uncomfortable to hold.
Isn't there severe issues with micro plastics doing this? Serious question. I've just heard in general on 3d prints that they're more prone to shedding.
If you do the smoothing steps it can be OK, especially if you sand it in a sealed environment or with a HEPA vacuum handy to suck up all of the particulates. Once it is sanded you can do a short acetone treatment and the surface will be melted smooth. It can take some practice, but you can seal it up pretty well without sacrificing quality. Just be mindful of air quality and filtering at each step so you don't undermine your goal.
Also, no matter what the microplastic impact on the environment is less than a mouse made in a factory thar doesn't pay attention to any of its air quality standards.
Gotcha. Thanks for the type up!
I would literally eat a spoon of microplastics if it meant I got a mouse that was comparable to my G602. Not saying this mouse does that but there certainly aren't any commercial options I could find.
need to take it real old, print it in abs and do a vapor smoothing in acetone.
You could also print this in a goo printer and not have the issue.
Interesting. I always wondered if the same rule applied to the 'goo' type as my friend has one.
They definitely don't shed much when they're new. They're quite playable and don't sand easily
Now you leave it in the sun for a year, they do get brittle, I suspect at that point you might be able to sand them on a table surface.
I keep thinking I should give a ploopy a shot but I've increasingly grown to like/need vertical mice and, like most ploopy related efforts, it is mostly "you CAN do it" with nobody ever having even tried because it requires pretty hefty redesigns of almost every part to mount things correctly.
I want an open source mouse with electromagnetic resistance wheel like one in Logitech MX Master 3S.
Might not be too difficult to achieve by connecting a small electric motor to the scroll wheel axle. Then you could vary the resistance by changing a pot hooked the motor's terminals.
I'm waiting for my MX to die to get one! I really like the idea of open hardware and this looks like a good mouse.
No left hand options 😪
Just turn the printer upside down, dummy!
Most slicers allow you to mirror parts very easily
The PCB doesn't look ambidextrous. Maybe there's a way to mirror that too but it's probably not as easy. And you'd have to get it custom built.
Ohh OK, yeah that would be tricky unless you're an EE
This stuff is nice. Are there any plans for a vertical mouse for those of us with cranky old man wrists?
You need plastic that is more resistant to contact so that you don't end up covering your hand in microplastics. That material looks like questionable recycled plastics.
I'm also not giving up on wireless. I'd rather have an only bluetooth (slow?) mouse than a wired one.
All the 3d printed parts have files available online. You can 3d print new parts using any material you want.
As far as I'm aware, PLA is mostly safe, but every company has different proprietary additives.
Something plant based like cellulose would be nice. Longevity wouldn't be a concern with how easy it is to reprint and reassemble.
Wireless would be nice.
Or titanium? But that would probably require midifications of the bendy bits to keep them flexible. 😂
I kinda like the idea of using an anvil to smith a computer mouse, but I don't have such tools. Perhaps carving the shapes from wood would be easier.
I'm not sure what makes it seem recycled, seems like a reasonably fine print to me. I believe it's printed in PLA which personally I'd want to see PETG but that's more for long-term durability than microplastic concerns, which I can't speak to.
I do agree with you. Except for the Bluetooth. Those mouses always need batteries and are empty and the mouse too heavy.
I am also a big fan of the MX518 lineage mice, so I hope someone make a version that has that shape. When Logitech released an updated MX518 several years back I bought a couple of them, so I will be good for years hopefully.
How do you like the mouse? I got their trackpad and it's pretty good. I'm thinking about replacing my old Mx Master with their mouse.
I like it. The surface finish is obviously not as nice as the Logitech, but I like it. I'd probably like it better if it were smooth, which I might try achieving with some epoxy paint. The button feel is great. Better than my G502. Tracking is stellar. The shape is comfortable. The infinite/togglable scroll wheel on the G502 is sonething I wish it had but I can live without it. There's also that special feeling, that someone decent made it, and that it can be infinitely repaired. If it's not a stretch money-wise for you - get one. In the worst case scebario your money would have gone supporting open source hardware.
I hope someone makes something like this that looks just like IO1.1
Ah great! My hands are big and all the mouses I tried are all too small. And it's giving me rsi. Hopefully this will help me. I theory I can just potentially print my own mouse design that finally fit my hands?
The PCB has electrical buttons permanently attached. The 3D printed parts have protrusions that touch the buttons.
You could possibly redesign the 3D printed parts only, but at some size increase you may need to start looking into redesigning the PCB.
The good news is that the mouse itself is bigger than the picture makes it seem. You might actually be OK without modifications.
If you do want to give it a try, I highly recommend buying the kit and fully assembling it yourself. That way you know that it works, and you have a solid foundation to apply the modifications to.
Good point. It measures at about 13x8.5cm.
You probably can modify the existing one to fit your hand fairly easily.
RSI is caused by repetitive motions. No mouse can help that. Look at exercise to combat RSI.
I have carpel tunnel syndrome on my right hand after using mice for dozens of years. It became so painful I learned to use a computer mouse with my left hand.
That worked for years until I squeezed a couple dozen lemons my neighbor gave me. Of course I used my right hand. Had pain I cannot describe, I could not function. The doctor had shoot cortisone into my wrist.
PROTECT YOUR WRIST
I want one
Mine arrived today, have you ever had issues where holding down RMB also holds down LMB with it? I've experimented with loosening the top screw slightly, and it's greatly improved this behaviour but I don't believe it's been eliminated.
Haven't noticed any issue. That said overtightening the top screw does cause the button cover to warp a bit.
I managed to resolve this by slightly loosening the top screw, they work fairly reliabily now. I need to look into perhaps increasing the friction of the scroll wheel, as I'm finding that sudden movement causes it to rock and scroll accidentally. I'm wondering if I could grease the ends of the scroll bar or something to that effect.
stumbled upon this really cool mod leveraging megnets to introduce some tactility to the mousewheel, I might need to pick up an FDM printer to experiment 😊
e: seems the revised model leverages magnets to increase friction only, but I think that would also work
Oooh this is very nice!
Does anyone remember the Microsoft Sidewinder X8 mouse? It had vertical thumb buttons instead of horizontal, and I loved that layout, but it's literally the only mouse I've ever seen like it. But now that I know there's open source mice out there, I might have to mess around and learn CAD so I can alter one of these mice to have vertical thumb buttons
I had the sidewinder keyboard with magnetic numpad that worked on either side. Loved that thing. Used the R.A.T. 7 Mouse 
though, fucking amazing. Best thing mad catz ever put out.
Ew
"These jokers" are giving the files and documentation away for free. They're charging for the cost of putting together a kit so you can build one without thinking or understanding anything. If you want it for cheap, self source and DIY, that's the whole point, that's why the files are free.
You don't need to pay them anything.
You can just download all the files they've made available and build one yourself. The electronics have full schematics so you can either make it yourself or send the schematics to a PCB company. The shell is entirely 3d printed. All extra hardware is readily available.
If that sounds like a lot of work, maybe it's worth paying the person who created it and is offering to do all that work for you.
How much should it be? It uses a great sensor, Omron main switches, it's built by two guys in Toronto, Canada where rent isn't cheap. There're definitely cheaper massproduced mice that don't share IP for free. This isn't that.
It's hand crafted, they probably barely breakeven.
Go ask Logitech if they will share blueprints or spend 0.10$ extra for a button that survives more than 100'000 clicks
I have a Logitech from 2003 or so. The feet are gone. The plastic under the feet is rubbed rmooth. The Omron switches are still great, no failure symptoms. Meanwhile I replaced a G500 after couple of years of use due to a switch developing "double-click" from wear. The reason I needed another wired mouse now is that another Logitech developed double-clicking. So yeah, exactly.
I have a 2 year old MX Master 3S, the left click button can't dragndrop anymore without dropping, unless you press really hard on it.
Also I can't rebind the buttons without having Logitech spyware installed on my computer.
Changing the button requires soldering and deep disassembly.
For a 120$USD mouse this sucks !
Using cheap switches on high end stuff like this is just abominable. I'd somewhat understand it on a cheap model but this.. fucking hell.
How else would they still stay in business if I could just use that mouse for the next 10 years !
If it only was merely aboit staying in business.. instead it's all about growing profits. They made $613M on $4.3B last year.
Chatgpt, give me the most business answer possible with airtight logic that eliminates the possibility of imagining a different way.
Chatgpt :
Logitech, like any publicly traded company, exists to maximize shareholder value, not product longevity, so using cheaper switches—even in a $120 mouse—isn’t corner-cutting, it’s strategic. A $0.10 upgrade per unit sounds trivial, but across millions of units it erodes margins significantly, and more durable components risk extending the product lifespan beyond the optimal refresh cycle, cutting into predictable repeat sales. Making switches hard to replace and binding functionality to proprietary software isn't anti-consumer—it's deliberate lock-in that ensures brand dependency and data capture, both of which are monetizable assets. With shareholders expecting year-over-year growth, not stability, any move that delays repurchase or encourages repair undermines the core business model. The $613M profit on $4.3B revenue isn’t greed—it’s the result of a finely tuned system where every design and pricing decision serves one purpose: sustainable, scalable profitability.
The robot knows what's up.
I had 2 Logitech m570s fail on me before I bought the Ploopy Thumb. So far it's lasted longer than either Logitech mouse, and looks like it will manage to be my longest surviving mouse.
