2024-06-17 (M) GrinderCompassMKIII REV3 cages

REV3 was the sturdiest print, with a solid bottom on the inner cage and a rounded square on top of the outer cage. I installed a magnet spinner with an M3 bolt and two nuts. Adjusting the tightness so the spinner could freely turn without wiggling took a few minutes, but it is a better option than adding springy material like I used in previous models. The current model's diameter was slightly larger than a D-cell battery. I still do not have any method for adding feedback, but I can worry about that when I get a usable mounting system.
