Raspberry Pi Case with Hex Bolts

I loved this design of pi-case but the original design did not stay together well and required trimming to fit nicely.

I've removed the GPIO access, removed the interlocking peices, and added rounded tabs on the side with insets to take a small hex bolt. I like the look of the bolts, and it is very secure without any fuss assembling.

For the bolts I am using part number 6374 from BoltDepot.com which is Metric socket cap, Stainless steel 18-8, 2.5mm x 0.45mm x 16mm
