The qInch Project : Double Ball Joint
thingiverse
Main Project Page : http://www.thingiverse.com/thing:668017 It's a ball joint that uses a clamping method to lock it into whatever position you need it to be. Hardware Used 1 1/2 inch 1/4-20 Bolt and nut. Whatever size bolt you want to put into the ball joint shell. ( 3/4 inch or 1 inch would work best when connecting to a camera or projector) Future Plans Going to do a variation on this joint where one side will be replaced with a rotation only instead of a pivoting ball. This would be more functional personally to hang my projector but might be useful to others as well. Freecad Source Included
