Gridfinity Blades Bin 2x1x20 half grid

This is a Gridfinity 2x1x10u blade disposal box with the base redesigned for half-step Gridfinity.  It fits the standard grids but can be placed on both normal and half-grid positions rather than the full the original used.  I also included corner magnet holes, which you could ignore and not use if you want.  I generally don't use them but I usually include the holes anyway in my Gridfinity prints.

It's fairly large, so will likely take blades for many years.  The slot is larger than I'd want for tiny blades but works great for blades out in the garage that don't fit in the sharps box I like to use for my safety razors in the bathroom.
