I recently built an enclosure for my Prusa MK3 and wanted a way to secure the LCD to the outside of the enclosure. The attached LCD supports will allow you to secure the LCD/controller with a screw.

As always, Fusion 360 source is provided in case you would like to modify the design for a different screw size or some other purpose.
Doesn't matter PETG
I used 3 perimeters, 5 top and bottom layers.
