3.5 floppy disk box

I created a base and edge connectors for a 3.5" floppy disk box There are files for the bottom; one for disks with one tab and another for disks with two tabs (square holes) in the upper corners. These lock into the base. Edge connectors lock into holes in the edge as well so even with one tab locked the box will be secured and hold together. I made some recesses in the bottom to allow for self-adhesive silicone bumpers that are optional. The recesses are 9mm in diameter and 1mm deep.
