Box Gap test

thingiverse

You print boxes frequently and want to know your preferred gap size for this purpose. You have a tool with six cubes displaying different gap sizes to help you determine what you need. The cubes are marked with numbers from 0.1 to 0.6, representing the size of the two-side gap between the box and holder. For example, if you use the 0.1 cube dimensions, which measure 19.9 by 19.9, and the recess in the holder measures 20 by 20, then the gap will be exactly 0.1 millimeter.
