This is designed for a Logitech M575 Trackball Mouse. Others may work, but the contour in the part is shaped specifically for this mouse.
I've been incredibly busy at work recently and I've notice my mouse wrist has started to feel some discomfort. I decided to make this angled rest for my trackball to keep my wrist at a more neutral position during my workday. You will probably want to add some sticky feet of some sort to the bottom to prevent it from sliding. I used 3M anti-slip furniture tape.
It's currently at 45°. If anybody wants a version at a different angle, just shoot me a message and I'll redesign it quickly to whatever angle you want.
Designed to print without supports. I printed solid in PETG.
