Quickly Fixed version of bobblejot's Ender 3 linear rail mod Supported Rail: MGN12H 300-320mm No Carriage Stops If your rail has plastic stops on it you can pop out the plastic stop that will be near the x-axis endstop switch. That way the endstop switch will be switched by the rail carriage. You will need extra M3 T-nuts and a assortment of M3 screws and nuts 8x m3 nuts 2x M3^20 [6x M3^6] or [6x M3^8 and 12x washers to act as spacers] This mod will shift the printer head forward a quick and dirty fix would be just shifting your magnetic or glass bed forward to match. I made this after wasting 4 hours of my life trying to install the original mod by bobblejot and realizing it does not fit correctly. One of the screws to install the plate to the rail carriage interferes with the original ender fan duct i suggest using a flat headed screw or using washers to add space between this mod and the fan duct or even just using only 3 screws to attach the plate to the rail carriage. Added 2 extra holes near the heat slots to help securing the nozzle heatsink to avoid the nozzle moving. use some screws and washers or even some twist ties to secure the heatsink.
