Spherical Gear

thingiverse

Small scad script to create spherical gear on 2 axis as seen there: https://www.reddit.com/r/woahdude/comments/o4sfab/active_ball_joint_mechanism_based_on_spherical/ play with the parameters to find right value for your specs. I didn't try to find formula for gear-radius, tooth height, tooth-radius and tooth count... but they are all inter-related. Some value dont render good result. Also... in preview mode the result seem hollow (at least here) but it will be ok when you render it. The script push a bit hard on scad preview. Added the monopole gear to go with. This is a beta-version for the monopole gear. It is done by literally printing (difference) the spherical gear over a cylinder. The resolution is low (10 degree increment) but kinda reach the limit of my computer. This result in small ridges on the sides of the grooves.
