Calibration Cube Display case

This is a 5 x 5 display case for calibration cubes. It can stand, be hanged up or glued to something. The openings are slighty larger than 20x20mm to enable for variations in test prints and also to ease removal of the cubes. There is a small stop to prevent the cubes to fall out, but it is only a small stop, so handle with care.

Designed in Fusion360 by an amateur. Prints ok, works well enough. Definitely could be improved (like the hanger holes, that take only small head screws).
