I am new to the FPV drone world, and I didn't really like the sharp gimbal ends that came with my first radio transmitter.
I remembered that I had a few silicone caps for Nintendo Switch joysticks, and a 3d printer lying around ;) So here your go!
I printed 2 alternative screw hole sizes: 2.8mm and 2.9mm. I suggest you measure you gimbal screws before printing: in my case the right and left screws had slightly different sizes.
Small detail: the 2.90mm gcode file contains custom layer change code for octolapse.
