Raspberry Pi 2 mount for 2 wheel robot chassis

thingiverse

I purchased a cheap 2-wheeled robot chassis which came pre-drilled with lots of holes but none were suitable for my Raspberry Pi 2 board. I designed this to sit over the centre of the chassis and be offset to allow access to the various ports and the SD card. It can be stacked with additional boards. Two of the chassis-side holes align with existing holes but you will need to drill two more - I'd already drilled these before designing the mount so took advantage of them. The mount is designed to be fitted using short PC chassis screws although cut-down flat head self-tapping screws may also work. I used 4x 3mm brass stand-offs which required opening up the Pi's screw holes a little. 2.5mm stand-offs might work with a little glue to hold them in place, avoiding the need to drill the Pi.
