Fan adapter for power supply for cr-10

Still with the aim of reducing the noise of my cr-10, I changed the original fan of the power supply by a more powerful model, the Noctua NF-A6X25 FLX.

As the latter is thicker (2.5 cm), it must be cut on the cover of the power supply to bring out a portion of the fan.

The part to be printed makes it possible to fix the fan despite a square cut of the size of the fan.
