Drill Bit Holder (Customizable)

This is a customizable OpenSCAD drill bit holder model. I included two STL files for big and small one, however I expect you to customize it for your needs in OpenSCAD. Parameters are pretty obvious.

I suggest to print a test model first with a single row and make sure holes are fit. Depending on your printer settings you might need to post-process holes with a drill bit (especially when printing without retract).
