Thumbstick replacements for your radio controller gimbals. 

Designed for thumb grip use as supposed to pinch grip. 

To be used with m3 threaded insert therefore should fit any controller that uses m3 threads for gimbals, in my case I am using it for a Radio master Zorro controller. 

Recommend printing at 100% infill with 0.1mm layer height. Brim may be needed depending on you bed adhesion.
