After recently acquiring a model B raspberry pi (finally!), i set out to build a case for it.
The goal was to make something that
- protects the Pi from damage
- Is heavy enough that the weight of the ethernet cable does not pull it off the back of the desk
- looks presentable.
I have been making lots of things with acrylic lately after discovering Plastic Creations in Fyshwick. It is a fantastic material to work with on the CNC after you learn it’s characteristics.
I chose to use 10mm thick acrylic for the Pi case because it is tough and pretty! I machined out 2 slabs about 120mm x 70mm with holes in the four corners. The slabs are held apart by 25mm stainless steel stand-offs (*AKA Advertising Nails) which i got made in China for me.
To buy something similar here in Australia was $19 PER STANDOFF! whereas i got them from china cheaper..
Next step was to polish the acrylic edges to remove tooling marks. I ran through 180-grit to 400-grit sandpaper and then”Flame Polished”the edges with a LPG/Oxy torch. The flame is run over the edge of the acrylic quickly enough that it lightly melts the edge without bubbling it, and the result is a nice shiny finish!
Finally, i buffed the edges for a bit of extra shine with brasso and put it all together.
I still need to work out a better way of securing the raspberry pi in the enclosure since double sided tape just feels a bit dodgy when the rest of the case is so pretty!
EDIT: As you may see in the comments on this post, there is already a similar case out there (very very similar in fact), the major difference is that the designer has a brilliant way of holding down the Raspberry Pi inside the case.
Great minds do think alike!

I don’t intend to market my case as i think that would be quite rude considering Ken Dakin already has a product on the market but if you would like to get one for yourself, i would highly recommend you buy Ken’s PI-STACK.
