2023-08-03 (Th) GrinderCompassMKII Functional flat frame

The first model I tested was too tall, so the pins could not capture the spinner. I estimated it was 2mm too long, so I changed the model and made a second that was 1.35mm smaller than that. I cut a second set of clamps and two more rubber band segments to go in them. The bolt holes in the corners were unnecessary since the clamps held the unit together. I designed jigs that would secure the faces together while I drilled out the pin holes, but they were only necessary for construction and will not be a part of the device.

I changed how I cleared the pin holes by starting them with a narrow file, then drilling them to become cylindrical. The rubber bands across the top provide suitable pressure to keep the magnet stable without restricting spinning motion. The endcaps were hard to align, so I may revise or replace those.
