Single UMD case/cover

Snaps on the UMD and protects the bottom from scratches. Also reduces the movements inside by pushing on the disk through the spindle window. Takes only 7g of filament to print.

Optimized for printing using 0.6 mm nozzle and 0.3 mm layers - though other configuration should work as well.

Fusion 360 files are included for those interested in remixing the model. The dimensions were taken from the UMD ECMA specs document.
