XL MCU Sandwich / buddy cover with fan and filter

After having a lot of crashes, I finally understood that one of the updates did actually put a lot more stress on the boards, indeed increasing temps there.

After a few research, I found a few covers on printables, but none matches my expectations, who were:

• keep the parts that holds the boards in position
• fan have to be at the higher pos
• air that enters the volume have to be filtered

Suggested Filter: https://amzn.eu/d/haqWow8

Suggested Fan: https://amzn.eu/d/hPzgNja

Suggested protection : https://amzn.eu/d/4TuqKG8

Fan can be connected directly on the board: just use the 24V input right behind the left cover, and let the wires go this way. Check Pictures!

Due to temp, I felt confortable to print this in Prusament PC, ABS or ASA would work, Not sure  about PETG, and definitely no to PLA.
