About this 3D model

This is the box that perfectly fit with the sextant in http://www.thingiverse.com/thing:355337. To assembly the lower part of the box you need 12 m3 bolts, nuts and washer. For the cover, you have to glue the 4 pieces with cyanoacrylate glue. The pin in the hinge is a piece of copper wire. I have printed all the parts in pla @ 0.4 mm per layer
