Replicator 2 Makerbot Extruder Upgrade Spring Tensioner

thingiverse

In my recent experience, my Replicator 2 had issues feeding filament despite the Makerbot extruder upgrade. I conducted a pinch test and found that I could stop the filament. Through various modifications, I discovered that the spring wasn't providing enough tension. To fix this, print a tensioner at 0.100 mm scale, placing it in the bottom notch for the spring and attaching the spring between the top and new tensioner notches. This may resolve extrusion issues for others.
