ball clamp basic design for multiple usage

Had multiple projects with ball heads to clamp.

Designed this for general use. The ball head can be dissambled. So if you have a part like a Gopro mount you can take it out and insert another one.

Simple enter the diameter of the sphere and the shaft diameters.
Size will be calculaded automaticly and it will use a suitable BSW (british witworth thread) thread from the table below).

2018-10-07 note:
Printed a part for usage and this time with the thicker swinging flaps around the sphere the grip-cover-part was too tight to get the ballhead in or out when the grip is on. Made 1 mm more in diameter (it could also be much more than just 1mm).
