Very cool. Would you be willing to provide an stl or even better a cad file? ThanksNot a whole lot of adding to the tank under corona lockdown, so I printed a "random flow generator" style nozzle for my return. After 24 hours to adapt to the increased flow the hammers and frogspawns are really liking it, and are nice and fluffy. Eductors are working, but I think I can get some more performance out of it by reducing the twist rate of the flutes, so I may model and print another version and tweek some things. I really should do some CFD on it but the setup is a bit more work to appropriately model the eductor effects.
Seemingly happy Hammers and Frogspawns with the new flow.
