Experimental Dual Gear, Quick Release, Extruder

thingiverse

I'm designing a 1.5M tall delta that demands an extruder capable of effortlessly pushing filament through a lengthy bowden tube, but existing solutions seemed overly complicated or lacked a quick release mechanism. This project uses a robust 5:1 planetary geared Nema 17 Stepper, paired with: * A sturdy 5mm rod * Five millimeter spacers for precise alignment * Ten-millimeter bearings to ensure smooth movement * Two MK8 Extruder gears for efficient filament processing * Two 13t Pinion gears sourced from RC cars for their high precision * Four barrel nuts (five millimeters in diameter) to secure the assembly * Two long bolts (also five millimeters in diameter) to provide additional support * Two Extruder Springs to maintain tension on the filament * A reducing collar that narrows a 5mm opening to an 8mm aperture To assemble this extruder, you'll need to drill out one pair of barrel nuts to enable them to slide along the bolt. The entire assembly mounts onto 2040 extrusion, but modifications may be necessary for other printer configurations. I've conducted some initial prints, and while they're acceptable, there's still much to refine in this new printer with plenty of bugs to iron out elsewhere.
