Rugged box insert for CNC Collets

Here's my version for cnc collets,.After wasting filament making a box with the holes for the collets in it and getting the size wrong, I remade it with an insert to hold the collets. Also had a lot of difficulty getting the lid on and actually broke one base attempting it. I ended up remodelling it to put a grove at the back of each hinge to make it go on easier. Made from translucent yellow PETG.

This model includes the collet lid and a blank lid Plus the collet insert and a blank insert for amending in Tinkercad or other CAD application
