Pure genius; love it!
Initially I tried using Blender and extruding 2d images but that always left me with a ton of cleaning up to do and rarely ended up manifold. Then I started using the Cookie Cutter Generator in TinkerCAD which is a custom made shape generator. While it was consistent and clean It was frustrating and not nearly as high fidelity as Cookiecad. The blade thickness was always too high. The numbers you used to adjust things like size were not pegged to anything meaningful like mm or inches.
Now my workflow is so simple and consistent!
Thank you!
