This is a fan shroud for the CR-10 OEM parts cooling fan.
This fan is intended to block the incoming flow around the nozzle, while directing turbulent flow to the part. No supports because it is hollow on the inside, and any drooping near the nozzle just increases turbulence which is good. This ended up taking 13 iterations to get to the current model, and it is still a work in progress.
This was intended as a remix, but I ended up redesigning the entire piece. The original had the half circle too far center for the OEM fan, and it was intended for an e3D. I didn't even use the original dimensions because importing it into Fusion360 gave me 200mm as one dimension.
I used https://www.thingiverse.com/thing:2160958 as the hotend fan cover.
If anything needs to be updated, please let me know.
