Simply, this case fits the DeWALT 17-piece Metric Tap and Die Set. The lid is snap-fit on this version, but I might add a hinged version at a later date.
0.2mm layer height, no supports, no raft, PETG.
I printed this in MatterHackers Build PETG, first to test my printer's capabilities, and second because I wanted a case that could take some abuse without cracking.
Obviously, be sure to print the lid topside-down.
I added a piece of 3mm EVA foam to the inside of the lid to cut down on rattling.
