ENDER 3 4040 ENDCAP ASSEMBLY GUIDE
After removing the LCD from the Ender 3, an exposed end of the 4040 aluminum exists. This print is meant to improve the aesthetics of the printer when you move the LCD from the aluminum mount.
There are 2 variations of the print: the Cup version and the Faceplate version. Each requires a Mounting Plate.
After selecting your print files & printing (print before removing the LCD from your Ender), fasten the 4040 Mounting Plate onto the 4040 aluminum extrusion using the same set of bolts that were used for the original LCD mount. Be sure to orient the piece so the other piece will slide on from the top.
Slide the other piece on from the top! Done!
