Extruder for geared motor

pinshape

This model was actually developed by Josef Prusa, but I made some modifications to ensure it works with a specific type of hotend from eBay. As this is an open-source project licensed under GPL, I had no choice but to license my work in the same way. The fixes I implemented are based on issues reported in the Prusa3 repository on GitHub (https://github.com/josefprusa/Prusa3). To assemble the model, simply print it and attach your hotend. You'll need a 608 bearing for the idler and some leftover shaft from your 8mm studding. M3 bolts with springs will press the idler against the body, forcing the filament onto the gear drive. The hotend you should be using can be found on eBay at http://www.ebay.com/itm/2x-HotEnd-Fully-Assembled-and-Wired-FREE-Hobbed-Bolt-RepRap-3D-Printer-Hot-End-/281065376447?pt=LH_DefaultDomain_0.
