Z-Axis Knob
thingiverse
A knob designed for M8 threaded rods of the Z-Axis on a Makerbot is available. Inspired by Zaggo's creation (http://www.thingiverse.com/thing:975), this knob has quick print capabilities. It was made hollow with 0.2 infill density using Hex, and although it had a tight fit, no tools were needed for installation. An optional step involves pressing in an M3 nut and securing the screw to the shaft.
