Nozzle for 120mm fans.
I have designed this due to the limited space on the top of my PC, so that the fan in the area can get fresh air from the side. I'm thinking about making another one and putting it on top of another fan to direct the hot air coming out of the case.
I printed it as seen in the images.
15% filling (maybe more if you are one of those who tighten the screws well)
Supports only touching the bed and 60º cantilever angle
