Hole and stud gauge

When printing very small features that need to fit together, you can't always trust the printer's accuracy. For example, a 2mm hole turns out to be a bit less than 2mm, while a 2mm stud is a bit more. To make the two fit together snugly, I had to increase the hole size to 2.4mm for the specific printer settings I was using.

This Thing will print a gauge with holes and studs so you can select the correct values for a specific object you are trying to print.
