Summary

This is a seriously cool case that looks really punk. It can be customized to many different sizes and configurations. If you''re going to tell me it would be more secure if the bolts were on the inside just remember it's plastic. Then go back and re-read the part about this looks seriously cool. 

Instructions

Make it any size you like! All holes are designed to fit M3 screws. If the pieces are a bit big for you, (currently 15cm square) you could scale the whole thing by down to 75% and then use M2.5 Screws instead. There is no latch included you'll have to work that out on your own. The hinges and handle can be used but, I would encourage customize it. Use M3 bolts with a nut to put all the pieces together. For the handle and the hinge at the back, Flat head  bolts may work best with the included hinges and handle.
