The file 'Z-axis Adjustment Knob 3D Printer Model' is (stl,FCStd) file type, size is 23.7MB.
A big knob to adjust Z axis. You simply need to add a screw to maintain the handle to the pulley, and 2x M4 screws (with their knobs) to tight it. FYI, I've printed it without supports at 0.2, and all was OK.
