I’ve been on a spree upgrading my workspace/living space. With a new workstation and working arrangement, I started getting annoyed with the mouse cable moving around and making extra noise.
So, I decided to build one of these:
Mouse Bungee V3 + V4 by mer_at on Thingiverse.

Now it doesn’t make much noise.
I had the printer time available and a couple of skateboard bearings already on hand. I decided to go with black filament to keep the aesthetic matching with other hardware around my computer and let it blend into the background a bit.
