This is a small case I made for the the GPS receiver base on a Ublox NEO-6M, as shipped by Unmanned Tech in the UK.

Update 11/08/2014: Added a bit more space around the parts to allow for slight over-printing problems stopping the lid from attaching. Added an option to create four holes in the base to allow for fixing to a quad. There is now also a configurable parameter tolerance, which is a distance that will be added between the lid and the base, and between the base and the PCB. The default is set pretty tight.
