Open source computer mouse by Ploopy
-
I needed another corded mouse and this time around I thought of @[email protected] and @[email protected] 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 want one

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.

Layer lines, too expensive.
Looks less comfortable than one of those 10~15€ brandless mouses at MediaMarkt

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.

Yes they are 3D printed
Poorly 3D printed.
The layering issue could be solved by orienting the object at a 45° angle

No left hand options
Most slicers allow you to mirror parts very easily

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 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 !wrote last edited by [email protected]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.

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.

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?

I could reprint the housing one day, when I get a printer myself.

You probably can modify the existing one to fit your hand fairly easily.
-
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.
I do agree with you. Except for the Bluetooth. Those mouses always need batteries and are empty and the mouse too heavy.

Ohh OK, yeah that would be tricky unless you're an EE

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.

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.

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.
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.

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.

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.
What I really want is this, but with a trackpad instead of a trackball.

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 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.
