Gridfinity Caliper Transport Box

A box for 150mm calipers, fully compatible (and stackable) with the gridfinity sorting ecosystem.The size of the box is 2 x 6 x 4 gridfinity units (W x L x H), assuming a default grid size of 42mm x 42mm.The hinges are either 3D printable with a soft TPU (85A or softer) or you can use a 1.8mm sheet of rubber (I had one laying around from a prior project), cut to a size of roughly 21mm x 41mm. The rubber hinges are held in place by four countersunk screws, 2 x M3x6 and 2 x M3x8.
