Ender 3 Pro filament runaway sensor, z axis endstop salvage - remix

cults3d

This is a filament runaway sensor for Ender 3 Pro which is re-using the z endstop switch. After I installed the BLTouch bed leveling I have one switch free to use for something :) It is cut in 2 and you need to glue it after printing. This is better, at least for me, than printing with supports because you can place each part in the best way for printing and get it clean and strong. Please refer to the pictures for assembly and mounting. It is really tight fit to the x axis bracket and aligns perfectly to the extruder hole. If you like you can put two short pieces of PTFE "Capricorn" tube on both ends to keep the filament "in the air". Original design is here: https://www.thingiverse.com/thing:3409178 Original design was misaligned to the extruder with almost 5mm in z, seems that Creality had changed the design slightly. Anyway, original design is not working for Ender 3 Pro. Print and enjoy :)
