Storage Box for 1/4" Hex Bits

A small M2.5 screw can be placed in the base to lock the box. The screw must not protrude very far (∼ 1mm). To open with the screw inserted, it can help to gently push on the sides of the box, slightly deforming it, 

Make sure you have good bed-adhesion. You can use a brim to be safe.

Use 0.16 mm layer height for printing.

No supports required.
