Case Shell for DT-Series Beyerdynamic Headphones

Wanted a hard case to stop my Beyerdynamic DT-770's from getting dinged up in my backpack. The commercially available cases were either too large, or required you to bend the strain relief grommet, which seems to invite problems, so I designed this shell. Two of these will hold DT-Series headphones with a bit of room to spare. I lined mine with some thin, soft leather; but if you want to add more padding, lining the shell with some 3mm EVA foam should do the trick.

The file called 'just shell' is what it says on the tin: Just the shell with no holes. Use this if you want to modify the design to add a hinge, latch, adapter clip, armadillo compartment, etc. The file called 'for straps' has the holes needed to sew on the leather parts as pictured in the photos.  

You will need a printer that has at least one print volume dimension of 270mm to print this in one piece.
