Adjustable Drive Block Upgrade for Replicator 2 and 1
thingiverse
Experiment with an adjustable filament grip pressure drive block for your MakerBot Replicator. Utilize a knob fitted to a screw to fine-tune the axial bearing's pressure against the filament. The design doesn't require a metal spring, relying on lever flexibility instead. Alternatively, use a rigid lever and compress a piece of rubber by the M3 x 35mm screw's tip. Test both flexible and rigid lever shapes supplied. Remember this is an experimental design. Instructions, images, and parts can be found at provided links. Enjoy your experimentation!
