Paper WindMill (4 wings in hub)

thingiverse

The wing panels are small and flat, but can be enlarged while remaining flat. Customize them using OpenSCAD script parameters. The code is divided into numerous mini-modules for easier manipulation. Alternatively, you can download, print, photograph your creation, click "I made one," or wait for the wings' shape change. If assembly proves challenging, refer to the ancestor design for a tape trick.
