Replicator 2, CTC, extruder upgrade compatiable with 12mm V-groove Filament Bearing

thingiverse

This extruder upgrade works seamlessly with both V Groove Filament Guiding Bearing (3x12x4mm) and a normal flat bearing (3x10x4mm). It's meticulously designed to be compatible with all CTC model 3D printers, including replicator 2 clones. The arm is remarkably narrow at the tip, allowing it to easily slide into printers equipped with a cover over the extruder motors - an issue that can prevent the spring from generating sufficient pressure on the gear in other designs. The base of this extruder upgrade boasts a flat profile and rests securely atop a metal washer for smooth motion. This low-friction design allows the arm to pivot effortlessly. A filament guiding bearing attaches snugly to a metal rod, with an optional nail substitution: cut a small nail 2.3 mm in diameter for an identical fit. This is an extremely straightforward upgrade with just two components to assemble - and we've rigorously tested its effectiveness. Don't worry if it doesn't match your specific printer; you'll find the 3D design file provided so that you can make the necessary modifications yourself. Feel free to make your adjustments as needed! We hope this meets your requirements, offering a stress-free upgrading process filled with peace and love for every maker's success.
