Raspberry Pi 4 Aluminium Heatsink Case - Upgrade Covers

thingiverse

The Raspberry Pi 4 uses a lot more power than it's predecessors, and it really needs a heatsink. I got this cool Aluminium Extrusion heatsink case for the Pi 4 from Pimoroni for £12. Lots of Pi shops sell them - Pi Hut and Adafruit also sell them, some places call them "Aluminium Armour heatsink case". I designed a couple of quick upgrades to the case. A cover and protect the GPIO pins (I'm running Octoprint, so I don't use the GPIO) and a clip on cover to tidy up all the USB & Ethernet ports. You got the 3MF files for printing and the Solidworks files (these are made on an educational licence, hence the non commercial tag here.) Photos show the case with and without the covers. I've based all the tolerances on measuring the one case that I bought from Pimoroni. It works on mine, If you find this is out of tolerance for yours, please send me the dimensions and I will be happy to modify the files. I'm printing in PLA 10% infill, 0.2mm layer and 2 walls. Pretty much any standard settings should work, they are easy to print parts in under 1 hour.
