Includes holes for magnets that do not need supports.

I printed this in PLA with a 0.6mm nozzle and 0.35mm layer height, which takes 2 hours, and looked great. Supports are optional for the large circle but having them led to a better print, and they were very easy to remove.

Note that magnets are basically required to stop the phone from falling over due to it being only 2x1 rather than 2x2.
