Impeller of my submersible water pump was broken so i make another. Not exactly same geometry of blades but work fine. I reinforced little bit structure. Fit perfectly. I printed with 5% supports in Cura so its easy to remove supports.
Added 3d file so you can edit the part on Fusion360
I had many failed details, so in V9 i changed impeller thickness and overall thickness and blade attack angle, i have only PLA to test it. I someone try it with other material pls write me.
