Inspired by http://www.thingiverse.com/thing:214669but with an easier to print ball head and a backside to the case.It features an M5 mounting hole in the base.The design is parametric, so you may change the mounting, ball size,... to suite your needs.Assembly:Insert front into ballhead and ballhead into base while the material is still hot and flexible.You may want to press the walls of the base against the ball with 2 fingers for a few seconds while it's cooling.
