Collet Holder

This is the sort of thing that the CNC router is great for. I wanted a simple way to hold the collets that came with the CNC spindle, there's 13 of them and it's easier to use them if they are stored in order. So I made this holder:

Each collet is in a hole that is made up from four holes of different radii and depths so the collet is held snugly.

Making this without a CNC machine would be a trial indeed and simply not worth it. With a CNC it's trivial, well almost.
