Single use safety razor blade disposal box

This is a single-use, disposable box for discarding used safety razor blades (Probably works for box cutter blades as well, but hasn't been tested for that use). Box should hold about 50 blades.

Lid is designed to be non-removable once connected, and box can be discarded once full of blades. Lid is designed so blades can't fall out once dropped in. Print with supports, and be sure to remove small supports under all four lid clips.

Lid tolerances are very tight. Once removing supports under the clips inside the lid, fit lid loosely on box and turn upside down on hard, flat surface, then use a rubber mallet or palm strike to push the box completely into the lid (you should hear a snap when the clips mate into the box).
