Bit sorter gauges
thingiverse
A couple of gauges to sort drill bits. The video for this projects is here: https://youtu.be/9bweTEK-LIg I printed flat on the bed out of PLA. You want it as stiff as possible so 100% infill is probably best. To get the holes the right size I had to set horizontal expansion in cura to -0.175mm. You can either play with this value a bit or print slightly smaller than the bit size and use a file to adjust the holes. Printing slower seemed to help get sharper edges along the guide. This could probably be improved though.
