Screwless Sphere Gears
thingiverse
The original design was Eccentric Sphere Gears (http://www.thingiverse.com/thing:6499), but I modified the SCAD files to replace screws with pins for securing gears to the center piece. Now, these gears spin without changing shape as they're non-eccentric. The STL files are print-ready (only 3 prints needed). For each set of large and small gears, you require four pieces, along with 'singlepins' (spheregearPins.stl fits plated prints only). Printed using a Replicator.
