2020 Touch Screen LCD - Slide in mod

I printed the v2 version of the Ender 3 / cr10 / 2020 7 inch Touch Screen LCD (not the one that combines the stock screen with a touch screen).

Since I didn't want to get any T-nuts, and in general like to keep screws and bolts etc to a minimum I made this simple remix that adds rails to the base so that the base can be slid in to place on a 2020 or 4040 extrusion (it attaches over a corner).

Due to the logical rotation for the rails some other details of the base were edited to increase printability.

Note that the base might wobble a tiny amount when attached, as soon as there's some weight on it (i.e. the screen) it settles and I've had no issues.

NOTE Since I wanted the screen on the left side of the printer I just flipped the parts, this works fine but makes the printed bold screw on the wrong way.
