I remixed Wersy's LCD case to add a mount to V rails which allows the case to be angled for better viewing from different positions. I also added embossed numbers in the back for the connectors to avoid confusion. Along the way I had to make a number of changes because the Reprapdiscount Full Graphic Smart Controller (sic) seems to have changed - panic button and knob are a bit different. I also changed the "grill" for the beeper as I didn't like the way the holes looked. Not sure mine is better, though! Could probably just eliminate it completely as it's pretty loud to start with. Also, the original front case needed some rework because the lip wasn't deep enough.
You may need to make some changes in the following areas: - The original knob was for a D shaft, mine was a press-to-fit one. Depending on how your printer printer does holes, you may need to resize the hole. - The panic button on my LCD board stood way too high so I had to rework that. I suspect there are different button switches being used so you may need to mod that. The fit is fairly tight - about 1/2 mm travel on the switch. - The V rail mount "fingers" thickness and spacing may need to be tweaked a bit based on your printer, - All the holes came out too small for me so I just drilled and/or tapped them.
Be sure to use the spacers (need 4) to prevent shorting the two circuit boards together.
Additional parts needed: - reprapdiscount full graphic smart controller+ cables - 8 M3x12 screws (edit: I've found that 4-40 1/2" sheet metal screws work great, too) - 1 M4x25 screw and nut - 2 M5x10 screws and t-nuts for mounting on the rail.
I've included the sketchup file. I imported the original .stl files and used cleanup on them.
