Teel Fountain Pump Impeller Open

Teel 2p403a pond fountain pump impeller. probably works with other models. Has about a 5mm shaft, I had to heat the little metal shaft up with a lighter for a few seconds to get this part on, it was just too tight. My pump has run for a few minutes with this part printed in PLA with no problems. The original impeller probably hit a rock, so I built a filter to stop that.
