Adjustable Drive Block Upgrade for Replicator 2 and 1

An adjustable drive block for Replicator for experimental use. Via a knob fitted to a screw, the pressure of the axial bearing against the filament can be adjusted and fine-tuned. This design does not need a metal spring and relies on the flexibility of the lever. Alternatively, it can use a rigid lever (supplied) and a small piece of rubber which is compressed by the M3 x 35 mm crew's tip. Two different lever shapes are supplied for testing between flexible and rigid modes.
