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.
