Heading towards a Raspberry Pi tablet, this is a case for a touchscreen LCD display that connects nicely to the Raspberry Pi.

Right now this case fits around the display as a separate unit from the Raspberry Pi, which you can put in any of the available Raspberry Pi cases on Thingiverse. My next step will be to fit the Pi into the same case. Oddly the thing preventing it is that HDM cables are so thick. Does anyone know where I could get (or parts to make) a flexible HDMI cable that's only a few inches long?

The design has been printed and iterated a few times, with the updates uploaded. Added a slot into which the power jack slides (bottom right side of the monitor), to better align the access hole on the back to the HDMI connector, and to enlarge the access slot for using the controls (bottom front). And added 'tabs' to hold the corners down. They eliminated curling when printing PLA (for me), but you'll have to break/cut them off unless you really like Mickey Mouse.

Still looking for an HDMI cable that's short and flexible, so that I can pack the Raspberry Pi into the display.

Buy http://www.benl.ebay.be/itm/Samsung-7-LED-LCD-Touch-Monitor-Kit-Out-Door-Industrail-Grade-Sunlight-Viewable-/110923590251?pt=US_Rear_View_Monitors_Cams_Kits&hash=item19d38faa6b . It is a durable 7" touchscreen with an HDMI input. It also has VGA and composite input, and it runs on a wide range of voltages, so it's used for in-car videogame and DVD player display, etc.

Remove all of the cables that you don't need (VGA, etc.).

Gently connect the video controller to the display (they come together, but aren't connected) and double-stick tape the video controller to the back of the display so that the connectors lie flat and the HDMI jack sticks out the back.

Print top and back v6 STLs.

Put display into the face, with the controls arranged below the display so that they're visible through the slot.

Slide the power jack into the slot on the bottom right of the display

Feed the USB cable through the HDMi hole in the back, and connect it to the Raspberry PI.

Close the case

Plug HDMI into the back of the display and into the Raspberry Pi. The connector should be directly below the opening on the back of the case.

Plug power into the display (the jack on the side).

Plug keyboard and power and an SD card with Raspian on it (download from raspberry.org) into the Raspberry Pi

When you configure Raspian, turn off overscan, so the display uses the whole screen.

Have fun!
