Use two of this screwless piece to hold your Smart LCD beneath the top part of the printer's frame.
The piece was originally intended to be fixed with screws, but it stays so well without screws that I just tapered two of the holes with "buttons" to keep the LCD in place. If you want to use 3mm screws you will have to remove these taps with a drill.
Warning: check your extruder setup and ranges for compatibility with this thing.
If you are a curious maker / "tinker" / hacker, have a look at my blog:
Made with sketchup.
See image in gallery for installation on the frame. Put the two holder's pieces on the frame prior to intalling the LCD.
