These covers will fit your 4040 4020 2020 extrusion etc, cut them to fit your dimensions or print multiple to fill a custom length. Simple and slide right in with a flush finish to the surface. The file names relate to the length of the cover. So '175.stl' is 175mm long. 135mm will fit perfectly on the Ender 3 for the front lower extrusions which hold the LCD and control box for the motherboard as shown in the image. If you need a custom length or modification please do contact me and I'll happily do it for you.
3D file format: STL
