Put it on a flower pot to amaze everyone!
UPDATE V2.3: 50% Thinner blades to offer less wind resistance. New attachment clips for better construction. Many thanks to Antoine Carbo for the improved clip design!!
The other day I saw a big metal pinwheel at a local museum that created a cool optical illusion when it rotated, I loved it...
I returned home and began to work on my own printable design. It took many prototypes but I think I nailed it.
The special twin blades rotate on opposite directions when the air hits them. The handle has a hole that fits a standard pencil so you can make it longer and stick it on your garden.
The blades do not require supports. The handle requires small supports.
Assembly Instructions:
1-Slide the blades to the pivots on the stick, making sure the flat sides of the blades are facing each other. Note: You might need to sand the pivots a little bit to make them as smooth as possible.
2-Place the washers on the pivots and snap the clips in place at both ends.
You can add a drop of oil at the center of the blades to make them rotate smoothly.
Insert a pencil into the stick's handle to make it longer.
