Joystick Cover PS5DualShock Switch
I tried it on the Switch and PS5 DualShock controller. The idea is it's one of those stick savers but also protects the top of the stick. Here's the file if you want to improve it or make it worse. I imagine it will also work with Switch 2 or xbox, the joystick stalk width is about 9.6 on the controllers I tried. It should be easy to hop into onshape and change the diameter for free if you need to change it for a PSPortal, for example.
