Magnet Fit Tester

Find the best magnet fit for your laser cut projects without measuring kerf or guessing at hole sizes.

Enter the diameter of your magnet and this project creates a centered set of test holes in slightly different sizes. Cut the tester from the same material and with the same machine settings as your final project, then try your magnet in each opening to find the fit you prefer.

Use it to test for a snug press fit, a flush glued fit, or a looser removable fit.
