Ender 3 Rail Shelf

This is a small shelf-like item that can slot into the front of the top rail of your Ender 3 (or any printer that uses the same rail dimensions (of which I am not an expert:) )). I use my quick and dirty ABS print to hold the adhesive magnetic strip that my USB LED light bar sockets to.

You'll want to print this as oriented, on edge. This is for strength. If you print it 90° to that, so it's flatter, the layer lines will be perpendicular to the supports, and it might snap right off at the notch flange. Any other orientation is a mess of supports.

For my purposes, and engineering considerations, I made it 55mm out, and 130mm long. Maybe you can find a use for it! Or just copy the flange dimensions for your own project, they are accurate enough that my first print fit snugly, with no wobble.
