Cooperation with the dimensional tolerance test

0.05 to 0.25 mm tolerance test.

Try inserting the round and square pins into each hole to see how precise the tolerances of your printer are.
 

Note: The tolerance applies to each mating surface. For example, for 0.1 mm, there is a 0.1 mm gap on each side of the hole, and the width of the hole is 10.2 mm.

Note: The width of the pin is 10 mm.
