The Pibow is a nice Raspberry Pi case made from layers of lasercut acrylic. This is a simple mod of the backplate that allows it to be screwed onto a VESA 200 mm mount, as found on the back of many flat screen TVs.(First photo shows the original Pibow backplate on the right, VESA 200 mount mod on the left. Second photo shows it mounted to my TV; note the round spacer under the bolt, and also that the Pi is powered off the TV USB debugging port :) )This file also has some spacers that help you to mount it without mashing the nylon screws that hold the case shut.There are also a couple superfluous pieces in the file; they were for a test I made of an interlocking Pibow layer designed to save wasted acrylic material. But you don't need those pieces for the VESA mount. They are just thrown in because that would otherwise be wasted space in this design anyway...The file format is ready to be sent directly to Ponoko for laser cutting. I believe the Pibow layers are 3 mm thick, which is a standard thickness available at Ponoko. Since this is the backplate and not an internal layer, it doesn't really /have/ to be that thickness, but I recommend it.You'll want two M6 metric bolts to attach to the TV. On my TV 16 mm long bolts work well.
