Gridfinity Hole Gauges

These are hole gauges inspired by Alex Chappels hole boards, redone to fit into two 1u Gridfinity plates.

How to use

Assuming you want to design a hole to fit a 5mm rod, then you can take that rod and test the fit for the different sizes. Most likely the rod won't fit the 5mm and 5.1mm holes, but it might fit into the 5.2mm hole, which in that case would be the size you should enter in your CAD model.
