Ender 3 X axis cover (with a belt straightener)

thingiverse

There is no news that Creality Ender 3 X axis belt is not parallel to X axis extrusion in stock setup. This addon fixes it. Also you can mount your X axis endstop 5mm to the left so your printhead will have more space to move (firmware update reccomended). If you wish to use sensorless homing, this addon lets you remove the X axis endstop and have this cover as a stop for the printhead. It will have metal part of the carriage bump the cover, not the wheel. Also this cover has low profile of only 20mm. Single piece version without belt straightener and an enstop cover are included You will neeed 4 M3x20 DIN912 screws, 1 M3x16 DIN 912 screw, 2 F623 bearings and a M3 washer. 2 M3x10 screws for the endstop cover or 2 M3x6 screws, if you don't want to use the cover. Before assembly, use 3mm drill to remove sacrificial layers. First put 16mm screw into the bottom part. Then install the bottom part. Put bearing + washer + bearing onto the screw, then put the belt on. Finally intall top part and fix it and the bottom part to the motor with 4 M3x20 screws UPD 21.12.07 Converted stl files to Thingieverse friendly. Replaced "bottom" part with the correct one. Originally, by mistake, uploaded another top part instead UPD 21.01.28 By request. I use this https://www.thingiverse.com/thing:3949808 tensioner to straighten the belt on the other side of the carriage
