Simple 'Case' For Raspberry Pi 2 Model B
More of a 'bumper' than a 'case' - something to protect the naked board whilst providing good airflow and reasonably open access to the connectors. Includes seat for 30mm fan above the chip.
I used M3 bolts + nylon stand-offs (16mm above, 6mm below) to complete my 'case'. It's worth noting that on my Pi, the board holes appear to be 2.8mm (7/64"), rather than 3mm, and so required a little drilling out to fit.
