2023-04-05 (W) GrinderCompass REV5 spinner design

I set to revise the spinner. The previous version had layers stacked upon one another like a laminated padlock, but this version would encase it. I designed the top and bottom with tabs and catches to hold onto the sides. The sides had notches and three holes for the axle. The idea behind the three holes was to slot a pair of nails into the top and bottom so the magnets would not shift when I inserted or removed an axle through the center hole. Magnet movement was a big problem in REV4. There are small holed rectangles that I will stack in the middle. The ends will be open since the neodymium stacks will hold everything in place.
