Prusa MK3 electronics bay cooling fan clip

Clip-on fan mount for cooling the back of an Einsy board on the Prusa i3 series printers. Multiple mounting holes are provided for different fan alignments. Intended to be used with the following parts:

BFB03505LA-C Fan

Connector Housing

Connector Pins

M2.5x6mm screws

The fan is plugged into the spare -5V connector on the Einsy board in reverse polarity. The lock mechanism for the connector housing seemed a bit tight on the board, so I removed it.

There are a few different variations of the clip. The "Angled" version points the fan more toward the stepper drivers, with Angled10 and Angled13 working the best for me. The number denotes the degrees below horizontal (Angled7 for 7 degrees, etc).

The "short" version brings the fan a bit closer to the board, but may be more difficult to install.
