Wera Kraftform Micro Gridfinity Holder (half pitch, fully stackable, very compact)

I made this holder for the Wera Kraftform Micro screwdrivers. I put a lot of emphases on compactness, each holding 7 screw drivers. There are many similar holders, but I wanted it to be half pitch and high density. I tried making it 3 units high, but I couldn't make it fit and be stackable. At least I managed to put 7 screw drivers per bin (only to discover I own 7x4+1 screw drivers).

The Gridfinity bins are 2 by 5 Gridfinity units and 4 units highs (31.8mm). The base is half-pitch, which means you can move them half a square, but it's fully compatible with Gridfinity. The screwdrivers are completely encased, so they are fully stackable too.

I'm uploading the 3MF and STL files, you should use the 3MF if you can. I also include the Fusion 360 file.
