This is my schematic, board layout file, bezel and back stl files for my Printrbot Simple Metal LCD Display. This should work with any 3D printer that uses Rev-D of the printrboard with thier firmware. I discussed this on their forums But printrbot has taken them down... I have left the link here in case the wayback machine archived it...( http://help.printrbot.com/Answers/View/9702/What+LCDs+work+with+the+Printrboard+Rev.+D#answer9885 ) Basic board build can be seen on my blog - AT THIS LINK (Yes, that is a wayback machine link as I had to close my blog) See the instructions for more details. THIS BEZEL WILL NOT FIT THE OFFICIAL PRINTRBOT LCD
Manufacture the board as laid out. Build with all components on the back of the board except the rotary encoder and LCD. Attach Standard 20x4 LCD directly to the base board with header soldered on both sides. Printed washers are to act as spacers between the LCD board and the manufactured board. Completed board assembly should fit into the bezel, add the back with M3x18 screws.
