Keep your controller pristine and get a competitive edge with these flexible thumbstick covers for the 8BitDo SN30 Pro+ controller.

There are several different designs for customization. My favorite is "ThumbstickCover_Grippy_Beefgrip.stl" and, of course, the "_Clown.stl"

These are generally designed for flexible filaments, but there are also "_NonFlex" versions of several designs made for PLA or other stiffer materials... Really though, the softer and grippier the material the better. Ninjaflex TPU works pretty well.
