Introduction: K'nex Windmill
If you any trouble with any step please put in comments below.
Step 1: Fan
Eventually this fan will be connected to a motor that will make spin. This is the easiest step.
Step 2: Front
This is the front part of the windmill.
Step 3: Back
This is probably the hardest step.
Step 4: Connecting the Front and Back
This is the final step. It's fairly simple.
