Wind indicator, without additional bearings.

Printed from PLA.

After printing the bearings gently hold and move them, then add some oil. 

The blades for the windmill should be printed with supports.

Bearings should be printed at a height of 0.18. The other parts can have higher values.

Some parts fit together very tightly and you need to use a lot of force. Be careful not to break the pieces.

At the bottom there are holes for screws, you can attach it anywhere or use zip ties to secure it.

Remember that printed bearings do not work as efficiently as metal ones. Depending on the printer or material, they may work in different ways.
