Difference between revisions of "RepRap Universal Mini Extruder (Q45348)"

This printable extruder is intended to work on RepRap Mendel (both standard and Prusa), RepRap Huxley, and virtually any other open-source 3D printer you can find. It features: 1. 1.75 mm filament 2. Adaptable mounting plate to attach it to virtually any 3D printer 3. Very compact high-torque NEMA 11 motor 4. Active ducted fan cooling for high reliability 5. Wade-style hobbed bolt filament transport 6. Wing-nut drive to spread the torque loading on the plastic gears 7. Push-fit hot-end parts - no thread cutting 8. Easily replaced PTFE liner for the hot end 9. A single M3-threaded rod cut to lengths makes all the fixings 10. Lightweight: 420g 11. Compact design (110 mm x 90 mm x 80 mm) I based this design (loosely) on Jstkatz's extruder (http://www.thingiverse.com/thing:7037), in particular, the idea of using a lever to trap the filament against its drive.
