About this 3D model

This is a case for [Bus Pirate v3.6](http://dangerousprototypes.com/docs/Bus_Pirate_v3.6) (DP6037 60x37mm PCB footprint). I found the design of the source thing _really_ elegant, but unfortunately it did not withstand the abuse I gave it and came apart too easily (esp when swapping cables, which I did often). So I made this, which looks almost the same but uses M3 screws and internal standoffs (top and bottom) to keep everything together snugly. OpenSCAD source included for further customization.
