Logitech M570 trackball pads

thingiverse

I lost one of my pads after a clean and thorough teardown of my Logitech M570. I'm starting to suspect that my mischievous cat is somehow involved in this mishap, but she's denying all responsibility. To replace the missing pad, I opted for 3D printing using Ninjaflex as a sample material. I attached it with a small piece of double-sided cellophane tape. Any flexible filament will do the trick, and regular filament can be used to maintain a basic level of grip, although it won't be as grippy as the original pad.
