This is a one third scale model of the Macintosh Quadra 700, the computer that was made famous by featuring in Steven Spielberg's Jurassic Park. One of my favourite vintage Mac models, I decided to create a full-sized 3D replica of the Q700 case, and after my first test print (at one third size) I realised what a great little Raspberry Pi case this would make.

So I created a remix of the model, specifically built at one third scale, with all the mounting and port holes for the Raspberry Pi. There is also a hole for running the power and display cable into the Pi.

The lid should just clip onto the base and stay there.

The fan mounting holes are designed for this 30mm x 30mm 5V fan:

There are two versions of the model, one with a mounting location for a mini amplifier and holes for speakers, and one model without these.

There are also two versions of the two base models, one with supports, one without. I create my own supports using boxes that have a 0.4mm gap (2 layers) between the model. This works really well on my printers, but may not work for you. You might prefer to generate your own supports.

Here are the speakers I used:

It's a snug fit, but the plastic speakers have a bit of flex so you should be able to squeeze them into their slots. Conversely, if they are a bit loose you can hold them in with a bit of hot glue.

I powered the speakers with this little PAM8403 3W stereo amplifier:

The little cutout in the case is designed to hold this little PCB in place. The pins on the amp are really close together, so it's a bit of a pain to solder.

Mounting holes are designed for M3 screws. 5mm screws for mounting the Pi, and 15mm screws for mounting the fan. Both fan and amplifier can be powered from the 5V output of the Pi.

You'll need good parts cooling to avoid stringing on the side grooves.
