This is an all in one case for a Raspberry Pi and touch screen. There are buttons on the side of the touch screen. Small 3D printed parts make it possible to use the buttons with the touch screen installed in the case. Five 3D printed buttons are required for the full assembly.

The Pi can be quickly removed (one screw) and there is room to make more connections to the Pi via USB.

The box was lasercut from .2" thick plywood from Home Depot. (purchased in 4x8 sheet). the OpensSCAD file is included and the material thickness is a single variable input in case you want to adjust the thickness for you material. The flat pattern can be exported from OpenSCAD as a DXF or SVG file.

** Don't get two 90 degree or two 270 degree. The 90 and 270 degree adapters bend in opposite directions.

I used #6 x 3/16 Long sheet metal screws for the screen but #4 might have been better. I had to enlarge the holes in the LCD screen a little bit to get the screws through.

The screw keeping the Pi from coming out is a #6 x 3/8 long sheet metal screw.
