Ender 3 Sliding Screen Mount

This is a simple mod to allow for the Ender 3 screen to fit on the inside of the frame and use the 4040 extrusion as a rail. There is an included cover plate to help keep dust off the screen when tucked away. The slider has a little flex and depend on your printer's tolerances on how well it slides. I've kept the design modular to allow for the use of a 14 cm linear rail in the future.
