Korg NTS-1 box

I made this design for a friend that needed to protect his NTS-1 connectors, since they seem to be not very long lasting.
I left the holes for the connectors small so people can use whatever connectors they find in their area (the ones I used could only be found in GB or China). These holes should be drilled or modified in a 3D modelling software to the necesary size.
There is also a small piece for adding a generic micro usb board, I think the pictures are enough.
