Ender 3 tray for Raspberry Pi and a DC converter

thingiverse

Thanks to the model I saw from GlassCurtain (https://www.thingiverse.com/thing:3026077), I decided to remix it by adding more supports for the aluminium printer base, extending the walls all the way to the top of the tray, and installing vents on every wall. To improve air circulation, I also lowered the back wall of the Raspberry Pi compartment a bit. The new supports for the aluminium printer base are designed to hold securely in place. Now, the tray slides smoothly into its position and stays firmly in place. From Admant77's model (https://www.thingiverse.com/thing:2935204), I adapted the fan guard to fit perfectly over the cover of the tray. Using a 5V Noctua fan powered directly by the Raspberry Pi, I've managed to lower the Raspberry temperature by around 10º C. I used this converter (https://www.amazon.com/gp/product/B0768D2NYH/ref=oh_aui_search_asin_title?ie=UTF8&psc=1) for my setup. I drew power directly from the main source for the 24V needed by the converter. The Noctua fan I used is available here (https://www.amazon.com/gp/product/B00NEMGCIA/ref=oh_aui_search_asin_title?ie=UTF8&psc=1). To help others fine-tune their own adaptations, I've included the Blender files.
