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'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.

I want an open source mouse with electromagnetic resistance wheel like one in Logitech MX Master 3S.

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.

[–] ggppjj@lemmy.world 2 points 1 week ago

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.

This stuff is nice. Are there any plans for a vertical mouse for those of us with cranky old man wrists?

[–] termus@beehaw.org 4 points 1 week ago

This is pretty cool. I make and 3d print pieces for my G502 to make it fit better for my hand/nubs. This seems like it has a lot of potential to design something better for me. That price is steep though but being disabled that's nothing new to me.

Most slicers allow you to mirror parts very easily

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.

[–] lightrush@lemmy.ca 2 points 1 week ago

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.

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?

[–] 18107@aussie.zone 5 points 1 week ago (1 children)

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.

[–] lightrush@lemmy.ca 2 points 1 week ago

Good point. It measures at about 13x8.5cm.

[–] lightrush@lemmy.ca 3 points 1 week ago

You probably can modify the existing one to fit your hand fairly easily.

I hope someone makes something like this that looks just like IO1.1
