Raspberry Pi 4 Aluminium Heatsink Case - Upgrade Covers

thingiverse

The Raspberry Pi 4 requires a significant amount of power, necessitating the use of a heatsink to prevent overheating. I acquired an Aluminium Extrusion heatsink case for the Pi 4 from Pimoroni for £12, available at numerous Pi shops including Pi Hut and Adafruit, where it's also known as the "Aluminium Armour heatsink case". To enhance the functionality of this case, I designed two quick upgrades: a cover to shield the GPIO pins (since I'm running Octoprint and don't use these pins) and a clip-on cover to organize the USB and Ethernet ports. You can access the 3MF files for printing as well as the Solidworks files used in their creation. Please note that these files are made under an educational license, hence the non-commercial designation. The photos demonstrate the case with and without the covers, showcasing how it looks when assembled. All dimensions were based on measurements from a single case purchased from Pimoroni, which worked perfectly for me. If you encounter any issues due to tolerances being out of sync for your specific case, kindly share the dimensions and I'll be happy to modify the files accordingly. To print this part, use standard settings: 10% infill in PLA with a layer thickness of 0.2mm and two walls. Printing should take under an hour using these parameters, making it easy to produce high-quality parts.
