ER20 Collet Holder

A simple ER20 collet holder that holds 23 collets. I have a cnc router, and wanted a nice custom holder for my collets that I have not seen before.I printed this out of PLA, Probably should have Printed out of ABS, but we will see how long this lasts.I can tell you that the collets fit perfectly. the fit is as if they were sitting in a collet extension. After it prints, Let it cool down before removing. It printed fine for me. This is my first upload, So please be kind. I am new to the 3D printer world. But I am not new to Machining and designing.Hope you like it.
