HexaDrill

A set of adapters to hold drill bits in a standard hex bit tool. Drill bit sizes 1.5, 2, 2.5, 3, 3.2, 3.5, 4, 4.5, 4.8 and 5mm are available. Each adapter needs two M2.5 screws that are at least 8mm long. 

The gcode and 3mf files include all sizes, and have a color change so the drill bit size is easily readable. Tested using PLA. Drilling was tested using a hand crank drill. 

This project was inspired by this excellent hand crank drill which only downside is that it cannot hold drill bits: https://www.printables.com/model/650099-hand-crank-drill-v3-vintage-eggbeater-style
