Fan blades

This is a fan blade for small electric motors. First time uploading. Be aware that this version doesn't give much wind yet. Please change the hole size in your CAD software. I will be updating new versions of this and improve over time. If you can, please boost me for support. ------------------------------------UPDATE------------------------------------------------------------------------------------------------------------------------------------Please do not print the first version as it is not fully optimized! Thanks! I will be publishing the second version! UPDATE-----------------------------------------------------------------------The second version is here with easier support removal and better stiffness. Boost MeI am new and I need support for me to make new models! Thanks!
