The file 'Ender 3 Pro Thin Rail Cover 3D Printer Model' is (stl) file type, size is 28.6KB.
This cleans up the look of the rail and protects the belt if you happen to grab it when moving the printer around.
On the original, a handful of comments talked about how the printer bed would run into it when the y axis was at 230mm+, so I removed the overhang section and cleaned it up a little.
