The design is based off the Black Nightmare plans found here (http://homepage.ntlworld.com/bruce.viney/Black%20Nightmare%20Plans.pdf)
I scaled the box by 1/2 and modified some of the dimensions to allow for clearance of moving parts and minimize the amount of additional part rework. Depending on your printer's accuracy, speed, nozzle you may have to sand or file some of the parts in order for smooth movement.

NOTE!!! The design as is has very small tabs (only 1mm in width) and some height differences (1.8mm to 2.0mm)If you are using a larger nozzle/layer height you may want to scale up the print. Additional. Test fit everything first before you glue the assembly. Parts will break if you try and force them together.

For assembly instructions use this link (http://homepage.ntlworld.com/bruce.viney/Black%20Nightmare%20Plans.pdf) Scale the distances accordingly (current STL's are 1/2 scale)
