Holes Sizing Guides

thingiverse

Removes the guess work for tolerances with holes. With this tool I can tell very quickly what size hole I need to model for a certain use case. For instance, I can tell that an M3 bolt needs a modeled 3.25mm hole to slide in snugly, and a 3mm hole if I want the threads to bite. The smaller one goes from 1mm to 10mm in 0.25mm increments, the larger one goes from 10mm to 20mm in 0.5mm increments. Print with whatever settings you usually use so that the tolerance requirements match what you'll normally need.
