This is an addon for EZ Drill Chuck by LoboCNC.
The original EZ Drill Chuck is awesome, but I was unable to use it to hold my smallest drill bits, the ones I use in miniature making. I made some small modifications to the original EZChuck-jaw file, extending one of the walls, and now the jaws can hold even smaller drill bits. I use these to drill miniature heads and gun barrels in my minis.
Just print EZChuck-jaw-small.stl file 3 times and use these jaws instead of the original ones. Nothing else was changed.
Also, I added a small handle that fits loosely into the EZChuck-base.stl. This way, you can use the entire Drill Chuck to hold heads on metal paper clips when painting. The idea is to print multiple EZ Drill Chucks and a single handle, and then simply replace the chucks holding parts when painting.
The author remixed this model.
