Overview:

Collet collars usually have a dimple or mark that you can use to tilt the collet in that direction to pop it out.  However, some don’t, and some can be stubborn.  I designed this simple tool to be printed in TPU to help remove the collet from the collar without doing any damage.

This was specifically designed for ER32 collets.

Printing:

Print it in TPU, so it will be tough and non-marring.
