Hollow Dice Calibration Cube

thingiverse

Someone on Reddit requested I upload this. Would love comments or suggestions for improvement. Every time I change the nozzle size, or try a new filament, I run a few test to make sure everything is dialed in. I normally print in PETG but lately been making a lot of models in PLA and been having trouble getting it dialed in. So I have a ton of calibration cubes lying around. I decided to make something more useful. This is a standard dice, but 30mm cube, so resize as necessary - 20mm seems to be standard dice size. It is hollow on the inside, and several of the holes intentionally line up with one on their opposite side. I think this is a good test for precision and overhang, which aren't tested well with the standard XYZ calibration cube.
