Modular Ball Joint Base

What started out as a way to test 3d printed threads ended up spiraling into a modular, adjustable base system.

Designing this, i went for a few things; a minimum of easily printed parts, a maximum of freedom of adjustment, and an easy way to attach other random bits to it. The first i feel was pretty well accomplished. The simple versions of this joint require just 3 easily printed parts, the more complex version still only needs 4. Range of movement is good as well, the simpler joints can go from straight to a roughly 50 degree bend, and the more complex panavise style base can go all the way to 90 degrees, with both styles being able to orbit freely. A simple twist of the nut on any of the bases securely locks the joint in place.

Attaching other bits and pieces is done with the threaded studs attached to the balls. The studs and the threaded version of the ball are modeled with a 1/2" ACME thread, meaning that anything with that thread can theoretically be attached to the bas
