Basically the same idea as the Gridbox by bilboDD but with holes for 6x2mm magnets. I also added some size variants to suit everyone's needs.
The box is made for gridfinity boxes that are full height. Make them at half height and you can stack them and maximize space. Check Gridfinity Rebuilt in OpenSCAD for quickly changing your gridfinity boxes to size.
Hinge and latch sizes are made to fit 30x3mm screws. I've not included the seals as they seem a but pointless for the task these boxes need to perform. I'll gladly include a seal if someone asks for it.
The author remixed this model.
