Bestway Impeller
Description
I remixed because it kept failing on me with PETG and my Ender 3 printing it. I went through several different iterations before coming to this successful one. My magnetic core on my pump, the little fins that lock into the impeller and spin it were worn down. I created two different STLs here to accommodate for a perfect version and a worn down one. That said, the worn down one I did have to lightly hammer on. BUT, it keeps it nice and snug. I also increased the shaft's outer diameter to fit more nicely in it's space and to add strength. Obviously changed the impeller to a curved design, and added chamfer and filets in every place that I could to increase strength. I also increased the overall length to fit better in it's place too. Previous versions tended to slip out a bit, which I think was causing wear. This one, for me, stays perfectly in place. Sorry I don't have any picture of the finished product, or it in place.
