Summary

I just want to make small cover for pin header only and protect two fan with big raspberry heatsink.
It will fit only on Raspberry Pi4 with this heatsink:

You can see in pics some jirkOS logo on it but do not worry i have created one with Pi4 logo as well. If you want to modify it, Fusion 360 file is included.
You can notice as well some other iterations there, its only to demonstrate that i was little bit struggling with it, i do not know why but it was quiet difficult to fit perfectly even if it looks easy:)
Maybe Jupiter was too close or some sun eruption i do not know why:)

Anyway, it should be easy print without supports.
