Description

PIvena is an Novena inspired Raspberry Pi case. It houses a 7” HDMI LCD and your Raspberry PI model B or B+. When the case is open the LCD is held at a convenient viewing angle and the Raspberry PI is easily accessible. There is a grid of holes over the free space in the bottom of case which can be used for mounting your PIvena modifications. The back has a rectangle cutout to access the GPIO of the PI. The Model B version also has holes for the audio jack and RCA video jack. The right side has access holes for Ethernet and USB. The left side features a slide mechanism that holds the screen in the open position.

Update 8/17/2014:
Added .stl files for all the wooden pieces

Update 8/19/2014:
Added parts for the B+ version of the case. Changes:
- The bottom plate has new holes for the B+
- The right side has a new cutout shape for the USB / Ethernet
- The back has an enlarged GPIO cutout and no more holes for video and audio since those connectors are no longer present on that side of the PI B+
- Assembly requires 2 more 1/2" screws and 2 more 4-40 nuts

Instructions

To make the PIvena you will need access to a laser cutter and a 3D printer. The PIvena is designed to be cut from 1/8" baltic birch plywood. The corners and hinges print great on my UP! mini and I've been printing in ABS, but I don't see why PLA wouldn't also work.

Hardware wise you need:
(36) - 5/16" length 4-40 screws
(11) - 1/2" length 4-40 screws (11 for the B+ version, 9 for B)
(4) - 5/8" length 4-40 screws
(6) - 4-40 nuts (6 for the B+ version, 4 for B)
(3) - 1" length standoffs
(4) - 1/4" length unthreaded standoffs
(1) - mini usb cable (it gets cut and soldered to the 2.1mm barrel jack)
(1) - 2.1mm barrel jack
(1) - 2.1mm barrel connector for the LCD screen power connection
(1) - 5V 2A power supply with a 2.1mm barrel connector
(1) - HDMI cable. I used a 1ft flat cable from meritline (http://www.meritline.com/1-foot-high-speed-flat-hdmi-a-m-to-hdmi-a-m-cable---p-75691.aspx)

The "all_parts printed" file should be the easiest to print from. I placed everything very close together and it should print great with no support material. The individual STLs are also posted.

The "pivena_lasercutter.svg" is for laser cutting. The lines are color coded for my laser and might need to be changed for yours. Red lines need to be vector engraved, blue lines get cut first, black lines get cut second.
