NOTE: Fusion 360 malfunctioned and exported a model that has to be scaled up to 1000% to be the correct size. Also, I wish I could include the F360 project file (.f3d) along with the model itself.

This literally is (on the outside) a hinged box with some rounded edges between the two halves, holes for plugging all the stuff in and some sloppily-placed ventilation holes.

For the hinges, cut a strip off of the filament spool (ideally 15mm in length), insert them in the holes, then use a 3D Pen thing (that is just the extruder, heater and some other stuff mounted into a pen-like chassis) to squirt(?) out some plastic onto the exposed pins (that were made out of a filament spool) to prevent said pins from being jostled out of the hinge mechanism.

For the Raspberry Pi, I think they're M2 screws? I pulled them (including the Raspberry Pi and the fan) out of an old PowerMac G3/G4-style case that was taking too much place on my desk (that's the main reason I made this in the first place, alongside just wanting an easier time swapping between microSD cards).

This case takes a 30mm fan (the same size that went into the old case), the screws appear to be about half a millimeter thicker (M2.5) than the Raspberry Pi screws. Those need to be longer, though.

I used this (https://www.***********.com/thing:3778297) as a "dummy" model to help me with all the stuff relating to measurement.

Also, about the logo on the "front": It's just the Half-Life 2 logo with the lambda symbol replaced with a pi symbol. It was recreated from memory, though. It's supposed to be like a logo version of my username.
