Noctua releases official 3D CAD models for its cooling fans

There is Fan Show Down on yt where people are trying to beat the original Noctua fan design:

> To protect our intellectual property, certain features – such as fan impeller geometries – have been slightly modified while remaining visually very close to the actual product.

Noob question: If someone wants to copy their design with no respect to their intellectual property, can't they just 3D scan?

That’s so neat! I will be able to compare to my own CAD models from when I 3d printed my PC :D

Would have saved me time on a 3D printer I designed a while back. I integrated Noctua fans and ended up measuring mounting dimensions by hand. Having the official CAD models would have made fan integration a lot cleaner.

How much more is the BOM for a silent fan like in Noctua? I recently bought a controller for my well water pump, and it has two 80mm fans for cooling. Sounds like an aircraft when taking off and doesn't seem to move much air. I'm planning to replace them with Noctua fans.

Mikrotik does this for some of their parts as well

The Fan Showdown YouTube guy is going to have a field day

Meanwhile 3D printing is being banned in US states supposedly to prevent people from creating gun parts, because just buying a gun in the US isn't doable for a criminal. But in reality it's because ownership of production and machines is about to get banned for the lower classes.
