This is an organizer designed to hold the various bits from micro sanders.

It is made to be printed in two parts with no supports, and glued together.

It can support up to 8 bits.

Rotating the bit can help lock it in place, the edges are sloped for easy access.

If you have not seen one before, these bits are designed for a micro sander that is similar to a dremel in size, but the movement is side to side instead of rotational.
