Tolerance and clearance test for metric M3 and M6 bolt/screw, M3 nut, and printed pegs (hexagonal, circular, and square). Every 3D printer will have slightly different dimensional accuracy. This simple print can give you a lot of information about what dimensions will give you a tight fit, loose fit, or allow a bolt to thread easily into the plastic. I still occasionally pull it out of my drawer for reference.

The first column on the left is the base size:
- M3 3mm diameter circular hole
