Tolerance Fitment Test

0.05 to 0.25 mm tolerance test.

Try insert the round and square pegs into each hole and see how good your printer's tolerances are.
 

Note: Tolerances are for each mating surface. E.g. For 0.1mm, there is 0.1mm gap on all sides of the hole, and the holes are 10.2mm wide.

Note: The pegs are 10mm wide.
