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:
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.
