Fortune Water Wheel

My first project. Water wheel for a water fountain. If this goes well I will design and upload a water fountain to go with it. Leave comments below on any changes you would recommend. In the photos I printed it in a single color PLA and pray painted it gold. Its been going well for the last week in my fountain. The pin hole size is 0.25in for the 4.5in version and 0.2in for the 3in version
