Sharpie Scribe

prusaprinters

Phoning in an 11th hour entry to the sharpie contest. Has not been printed yet, but model to be updated once the print has actually completed. Uses 2 M3 heat-set inserts. 1 to secure the foot to the ruler, the other to adjust the brake-pad pressure.Requires a well calibrated printer. Tolerances are for 0.4mm clearance from my particular brand of carpenter's ruler. YMMV.Features a double taper to allow the sharpie to point in either direction, relative to the pointers that indicate position on the ruler. This means you can use either the metric or imperial side.Print one of each part, install heat-set inserts and clear out any debris in the hole that might interfere with smooth operation of the brake.
