Octoprint - Raspberry Pi3 case with internal Noctua fan

This is an update of my last job you can easily find following this link:

https://www.thingiverse.com/thing:4371620

It is almost the same, but with Noctua fan positioned INSIDE the Raspberry case. This grants a much more good looking and a better order to the whole job.

I aimed to obtain what follows:

active cooling with Noctua 40x10 5V fan
less possible hardware needed to mount it
shape to hook to Prusa MK3S 30x30 alluminum extrusions
very good air flow

Components needed:

Please double check you'll purchase 5Volts fan.

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).
DOUBLE CHECK POLARITY, 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 !
