GoPro ball joint mount

The thread of the first nut (as from '3D_CC_design's thing) was too tight. It is modified a bit so this one is 1mm larger and fits well. The hole in the base piece was too small, so this hole is 0.8mm larger. Glue the base to the pin of the ball when the nut is in position.

To be printed with 100% fill, 3 shells, 0,1mm filament layer height, without raft or supports.

There is also an improved version for the GoPro 3:
