gridfinity scalpel box

This is my attempt at a #gridfinity storage solution for a scalpel. The scalpel ist stored in a 1x4x2 tray. The lower box includes storage for a whole lot of replacement blades and a box to safely store used ones. Combined with the tray it forms a 1x5x6 gridfinity element. The lid for the sharps box is screwed on using 2 m3x10 flathead screws that allign with the magnet positions. You will also need 2 m3 hex nuts. The overhang on the fresh blades storage will need supports, everything else should print fine without them. Why combine storage for fresh and used blades in such a whacky block shape? The idea behind this is that you can carry everything you need to use the scalpel as one unit, but still keep the scalpel tray itself a seperate piece.
