Matt McWilliams ce505d83c6 Center the mount plate and also create a "minimal_mount" module for incorporating this into other SCAD files. The idea being that this is a centered mount for a motor that can be dropped into different designs. 2022-10-10 08:43:35 -04:00
Matt McWilliams eb2f452431 Add a slot for an m3 nut as a set screw in the magnetic coupling 2022-10-10 08:42:36 -04:00
