About this 3D model

This very simple tiny Thing allows a quick and very precise calibration. This innovative approach consists in: - FIXING the endstop once and forever to the printer structure. - Doing the calibration by means of a small and accurate M2 screw (0.4 mm per turn) mounted on the part that moves towards the endstop. - Enjoying NO PLAY/slack. Sample application - Prusa i3 Z-axis endstop (see pictures): - Z-Endstop fixed to the metal frame. - Thing holding the M2 screw fixed to the bottom of the right X-end. Note: I have removed the metal lever from the endstop, leaving just the button; this improves the accuracy.
