3x4 Gridfinity Storage Trays

I really liked the Steintrack storage trays, but I'm already in the Gridfinity ecosystem and currently they are not compatible. I wanted a 3x4 Gridfinity tray for storing my mechanical keyboard switches. Some trays I can fill up with just one type of switch, but others I wanted to be able to divide up. I wanted to be able to stack the trays but also have them easily align next to one another, so I have incorporated four 10x3 magnet slots on each side of the housing. Finally so that you can stack other Gridfinity things on top, I modified the top tray to include a 3x4 grid as well. There is also a riser that fits the bottom of the case, should you like to raise them up.
