Octoprint - Raspberry Pi3 case with internal Noctua fan

This is an update to my previous job that you can easily find by following this link: https://www.thingiverse.com/thing:4371620. It's almost identical, but with a Noctua fan positioned INSIDE the Raspberry Pi case. This creates a much more attractive and better-organized overall project. I aimed to achieve several goals: * Active cooling using a Noctua 40x10 5V fan * Minimizing hardware required for mounting * A design that hooks onto Prusa MK3S 30x30 aluminum extrusions * Excellent airflow To build this project, you'll need the following components: * <a href="https://www.raspberrypi.org/products/raspberry-pi-3-model-b-plus">Raspberry Pi 3 B+</a> * <a href="https://noctua.at/en/products/fan/nf-a4x20-5v">Noctua 40x10 5V fan</a> Please double-check that you purchase a 5V fan. The fan is attached to the case cover using its own soft silicone anti-vibration mounts, which come with the fan. To connect the fan to the Raspberry Pi, use the GPIO port and the connector found in the fan box (refer to the enclosed picture for details). Double-check the polarity, as I had to swap the 5V and ground cables on the fan connector (check the GPIO scheme in the pictures). You'll need the following hardware: * 4 M3x18 (or M3x20) screws * 4 M3 hex nuts I used screws and nuts from a Prusa hardware spare bag, but they're common items. The Raspberry Pi 3 B+ fits into the 4 pins on the bottom case and is held in place by the case cover itself. The cover is secured with 4 screws and nuts. In the end, the entire case is designed to hook onto the 30x30 aluminum extrusion on the right side of the printer. Happy printing!
