I have designed this part to cool the motherboard of the MK3S when using an enclosure.
It allow to avoid crashes due to over heating.
2 fan adapters for 30mm and 40mm fan (for example Noctua NF-A4x20)
When using an enclosure, fresh air will be aspirated outside the enclosure and streamed to motherboard.
The Rambo fan adapter will fit only when using standard antivibration feets.
For others feets, you will need to use the Rambo fan adapter with lock and the Locker.
=> remove self support on top with a cutter, and gently insert the locker in the hole before to install and lock it to the frame.
(I use gaffer tape to keep the right vertical side closed to the motherboard box. Until now no problem with X axys for me.)
