ER20 Collet Holder

thingiverse

Collet clamping system loosely inspired by PRIma's system but made from scratch with a whole bunch of changes to make it fit traditional ER20 collets that you might find in your shop, and my own custom thread for 3d printing better (only 47 degree overhang with asymmetric threads). I have made 2 and they came out beautifully. They hold the collets really tight and so I included a hole in the bottom which you can release them with, we have just been hitting the bottom of the collet with soldering brushes. I included the design files if you want to take a crack at it, but they are solidworks files. I may be able to add more file types upon request.
