PLA Cube Gears for Replicator 2

thingiverse

To resolve the issue of Emmett's Screwless Cube Gears being incompatible with PLA, alternative pins were designed. Initial attempts with flexible end tabs failed due to short cube gear axle support. Subsequent redesign included altering pin tip structure for flexibility and reworking protrusions. These new pins are compatible with Makerware, ReplicatorG, and Skeinforge, snapping into place with moderate force and rotating freely. For those who already have Emmett's Screwless Cube Gears, simply download and print the PLA-gear-cube-pins.stl file as a replacement. For creating PLA cube gears from scratch, print two plates: PLA-gear-cube-plate1.stl and PLA-gear-cube-plate2.stl, with first plate featuring snap-off ear raft print aids to prevent gear breakage during printing. Recommended settings for both cases are at least 0.2mm layer height, 3 shells, and 15% infill, with skin module used to achieve 0.1 mm outer surface finish in ReplicatorG. The featured print was made using Makerware (default medium settings) on a Replicator 2, replacing the original pins that broke.
