Notice:
Tagging this as work in progress, as the duct currently collides with one of the screws on the mount (I softened the plastic with a jet-torch when mounting, to get around that) and I want to double check the dimensions again.
Fan duct do direct air to the nozzle from 3 sides with a 5015 fan mounted in the Original location.
For mounting information see: https://www.thingiverse.com/thing:5557113/makes (the straight edge of my fan sits pretty flush against the pcb)
I uploaded a stl file for printing and a step file for remixing. The original Onshape Document can be found at: https://cad.onshape.com/documents/a1d4c8b84c704bba94c46f6f/w/db4f3b014d7243c88c661a93/e/766a52528554cad413f61c36?renderMode=0&uiState=63b59bfc7ca77267020c58b2
I currently don't have a photo of my printed part, as it is mounted in the printer and I don't really want to take it out again :D
Remixing welcome.
The author remixed this model.
