Octoprint - Raspberry Pi3 case with Noctua fan
Description
Let me start to thank user 0110-M-P from Thingiverse for sharing his work in Thingiverse: https://www.thingiverse.com/thing:922740 I remixed his great job to obtain following results: * active cooling with Noctua 40x10 5V fan * less possible hardware needed to mount it * shape to be hooked to Prusa MK3S 30x30 alluminum extrusions * some mods to air passage Components needed: * <a href="https://www.raspberrypi.org/products/raspberry-pi-3-model-b-plus">RaspBerry Pi3 B+</a> * <a href="https://noctua.at/en/products/fan/nf-a4x20-5v">Noctua 40x10 5Volts Fan</a> <b>Please double check you'll purchase 5Volts fan.</b> Fan is fixed to case cover using its own soft silicone anti-vibration mounts (provided with the fan). Fan connects to Raspberry through GPIO port, using the connector you directly find in the fan box (pls look at enclosed picture to recognize it). <b>DOUBLE CHECK POLARITY</b>, because I had to swap the position of the 5V and GROUND cables on the fan connector (please check GPIO scheme in the pictures) Hardware needed : * 4 - M3x18 (or M3x20) screw * 4 - M3 hex nut I used screws and nuts directly from Prusa hardware spare bag, but they are really common stuff. Raspberry Pi3 B+ just fits into the 4 pins in the bottom case and is kept in place by the case cover itself. Cover is kept by 4 screws and nuts. In the end, the whole case is made to hook to the 30x30 alluminum extrusion on the right side of the printer. Happy printing !
