40mm XYZ Calibration Cube w/ Engineering Fits

Yet another test cube, this time it includes a test fit of two objects. With the tolerances in 3D printing being much looser than in machining, we can simplify the fit of parts to three categories. Clearance fit, transition fit, and interference fit. Printers and filaments vary in tolerances, if you need a wider or tighter fit to achieve your desired result, note the clearance required and adjust your prints accordingly.

Here are the following fits described:
