Noctua has released 3D CAD models of many of its fan designs, which is good news if you're 3D printing a project that plans to make use of them. You won't be able to print a straight-up clone, though, as the company has deliberately modified some of the crucial details, like the fan impeller geometries.
Noctua says the CAD models are provided on an "as is" and "as available" basis, with no warranties or guarantees, and that the models have been released "solely for reference, visualisation, and integration purposes."
