Bestway pump impeller 58389 (5678 L/H)

This is a model of Bestway 58389 pump impeller you can print.
I works. I've had mine for 2 months so far. (photo is slightly different because part got thickened and i couldn't make a new photo as it sits in my pump)
You need to use 100% infill. Use supports. I used PLA for mine, but PETG should work better.
