A test coupon for dialing in a desired press fit for cylindrical magnets. Sweeps a 3x3 grid of diameters and depths.

Set up for a stack of two 10x3mm magnets, so the sweep covers (10.05, 10.07, 10.09) mm diameter x (5.55, 5.60, 5.65) mm depth.

Embossed little/big circles and rectangles help you orient the axes and direction on the test print.

Fusion 360 file included for customization to your use case.
