Z axis adjustable endstop - Prusa i3

thingiverse

This custom endstop is tailored specifically for seamless integration with the Z axis on Prusa i3 models, without any alterations to its underlying mechanical framework. Simply attach and fine-tune as needed. The endstop's construction centers around two primary components: a clamp securely fastened to the left vertical smooth rod that supports the microswitch, and a mounting bracket that houses the adjustable plate, attached directly to the free-threaded hole on the X axis stepper motor. Notably, I created this 3D model with metal nuts embedded in a plastic shell. Remember to pause the print process at the last opened layer, then insert the nuts by hand (as depicted in the accompanying image) before resuming the printing process. As I encountered difficulty sourcing M2.5 screws, I opted to enlarge the diameter of the endstop to accommodate the use of M3 screws instead.
