extruder fan air channel for geeetech prusa i3 mk8 & AutoLevel

I have re made the Extruder fan by "thegman" with the following modifications:

1. intake is closer to the heat sink.
2. output port is directed more towards the extruder.
3. Added a servo housing for auto level the Z.

This is a work in progress and I will upload the files, pictures and the software when im done.
