Screwless Cube Gears (Q54426)

*** Last Update October 30 2011 *** I found that the large gear clip sockets were too deep- they came too close to the top of the part and I have quite a number of large gears with the corners snapped off. SO I hacked them up in openscad, making the clips and sockets parametric. I also added an option to round the corners so they can be given to small children. I have rebuilt the center piece in openscad so now it can be made parametric, and have a proper clip socket profile. I have arranged all the pieces into a plate. Approximate plate dimensions are 150x150mm. TODO: * redo the gears themselves in openscad using the excellent gears library in mcad, for a fully parametric cube gears! WIP: not printed yet!
