3 parts I use to test the dimensional tolerances from slicer settings.

Cube: 1"x1"x1" cube, with directional labels

OD Test: Piece to test outer diameters of circles: .750", .500", .100"

ID Test: Piece to test inside diameter of holes: .750", .500", .100". Also has 1" OD

Print Info:

Set Z-Seam to sharpest corner. Otherwise, these are to test your own settings.
