Logitech rubber coating: 2-year lifespan.
Me: Fine, I'll do it myself!

3D-printed a new shell in soft black TPU (on gray-ish PLA supports) and it fits like a glove. Honestly feels better than the original!

DIY > decay.

MX master 3 rubber shell replacement by Rikkarlo

The MXmaster 3 mouse from Logitec is by far my favorite mouse in terms of features and ergonomics. It's covered in a terrible rubber material that degrades between 1 and 4 years and becomes sticky and oily. Logitech does not sell spare parts, and adhesive skins after a while leak stickiness from the junctions (I tried them as well).So I decided to solve the problem by myself and model a new outer shell for my mouse.This solution is the best I've tested so far (and believe me, I tested many). Since I want to fight programmed obsolescence and contribute to a world with less electronic waste, I decided to share it for free. Feel free to print it and share some pictures of the results with me.

Thingiverse
@fribbledom very nice! Does the thumb-button at the bottom still work? It's the one, that I rarely use, but I could imagine, that it needs a soft rubber shell to work

@TheConstructor

Use it hundreds of times a day to switch virtual workspaces. Works just fine with TPU, if anything the material is a bit softer than the previous rubber.
