Pusa MK3 Z-Axis Gauge

thingiverse

Another useful gadget for printer enthusiasts! You can monitor z-axis movement or e-axis action with this handy tool. The two parts assemble perfectly without the need for glue, but a small magnet of 8 mm diameter must be secured in place. To ensure precision, I printed these parts at a slow speed (20 mm/s) and high resolution (0.1 mm layer height). This gauge should fit any standard NEMA17 stepper motor.
