A mouse that I find comfortable because it has a longer back to support my hand. It also doesn't have that "ergonomic" shape which I find doesn't fit every hand and you can't use it with your left hand. I made this because the mouse that I have now is starting to fail and I wanted to have one that people would notice. I didn't want to spend a fortune and making it myself just gives it that personal touch that I wanted.
This mouse uses the bambulab wireless mouse kit: https://eu.store.bambulab.com/nl/products/wireless-mouse-components-kit-002?id=47895575920988
Preferably, you should print it in petg but pla is fine as well. Here is the tutorial on how to put it together (they use a different body) https://www.youtube.com/watch?v=lkOg_X4qjW8 When I have my mouse I will make a video and change it to that one.
The printfiles.3mf is somewhat optimised with supports and stuff. The printfiles.step is just the components.
