BAIR - Berd-Air Prusa Bear Fan Shroud

I wanted to use Berd-Air on my Prusa Bear for months. With a bit of fiddeling, I created this fan shroud, which fits 4mm brass tube.

The dimensions of the tube can be seen in the image collection. I'm pretty unsure about the holes and their optimal direction. Maybe one has a better hand for this than me.

To bend the brass pipe, I used this tool: https://www.thingiverse.com/thing:2826538
(Important: Heat the pipe in the area you want to bend)

Also, one could use just two brass pipes without bending them - so the direction of the holes could be adjusted afterwards.

To hold the bear pump on my Prusa, I will use https://www.printables.com/de/model/161344-berdair-air-pump-holder-on-2020-aluminum-extrusion.

Printing:

I used ASA from Bavaria Filaments. Don't know whether PETG would also be good enough.
