Just created this double duct thing to get better printing results. It's flat so it's easy to print and use. No need of later processing because of supports.
I printed it with 0.1 layer height with 20% infil. This thing works really nice. Use up to 100% of radial fan speed without too much pressure.
This thing is created with 10x size. Don't forget to scale it down to 10%!!!
V2 is scaled correctly. Dont scale it down!!!
Next version: 2
smaller surface on build plate
more curved design
- maybe a slope at the vertical duct
smaller model file (less lines in model)
proportion of 20/80
Print slowly to avoid overhang on bridge parts.
