This is a rotating propeller as a keychain. I designed it to have something that represents the possibilities of 3D printing.
This design is free for everyone. You can choose between a 6 or 12 bladed type propeller. Printing time is less than an hour and somewhere around 10 grams of filament is needed. You can easily snap the propeller into the casing.
As always, I design our 3d models to be printable without support material.
