This LCD controller cover is specifically for mounting on Rigidbot. It is designed for RepRap Graphic Smart Controller available from http://reprap.org/wiki/RepRapDiscount_Full_Graphic_Smart_Controller. The base plate screws on Rigidbot frame and securely holds display at 0, 30 and 60 degrees. A better case for this LCD is available from http://www.thingiverse.com/thing:87250 and has dozens of variants, if you are looking for non-Rigidbot application. The back and front cover does not have screw holes to accommodate for PCB variations and should be drilled after marking. To mount it to frame, I drilled with 3/16" and used 4-40 tap and 1/2" machine screws. Rhino 5 model included. Instructions on how to install LCD module to Rigidbot board: http://rigidtalk.com/wiki/index.php?title=LCD_Smart_Controller.Front cover can be printed at higher resolution (0.16), back and plate can be rough (0.20) Print backcover and support plate with 100% infill.
