Spring Arm for Replicator (the ol Woody)

thingiverse

I inherited an old Replicator that had been stuck in a box, waiting for its next print job. After updating the firmware and installing whpthomas's impressive extruder upgrade, I was finally able to start printing again. I swap out filament frequently, but one day I noticed the unmistakable "thunk-thunk-thunk" sound of a stepstruder struggling to push filament through - and it wasn't getting the job done. Determined to find a solution, I designed this device. After creating it, I discovered that others had come up with similar ideas online. I was impressed by their creativity and innovative designs. This one's my own design, and I've spent around 50 hours of print time calibrating and refining it - without any slips or "thunk-thunk-thunk" sounds once set up. While I'm sure there are better, more sophisticated, and sleeker designs out there, this setup has been working for me so far. Happy printing! Print Settings: Printer Brand: MakerBot Printer: MakerBot Replicator Rafts: No Supports: No Resolution: 0.1 Infill: 100% Notes: I used readily available materials to build the spring and bolt, and you can see specific details in the pictures. To print this device, follow these steps: - Print out whpthomas's Pin and Base. - Assemble them according to his instructions, leaving out the spring arm. - To get the left extruder base, simply mirror the .stl file from his design.
