Propellers Pitch is Around 24-29 inch in 14.5 inch Diameter.
This is 3D-Scanned from Offshore 1.3 Race boat Class Propeller which is 17 foot long two seats race boat class with speeds above 80 knots, my sister drove in this class as an official racer when I was younger, and I just have had these kind of boats only for fun and hobby.
That hobby I have missed, but am gonna make now an electric speedboat, which charges it's batteries from natural power sources at sea.
I would like to give a challenge for some one to create equal propeller but left handed still with this same structure and measures, that I could get two of these same propellers into two side by side motors into that electric speedboat project.
I don't know anything of these 3D modelling software things my self, that's why am asking help. I promise to post pictures and info of the project for the one who gives the "mirror"- propeller for me, I guess it's not really so hard to do, there can be even one button for mirroring object but idk.
But to make totally equal propeller would need metallic printer, I have been consulting in the innovation one Finnish company named prentashop in 3D-metal printers design since last autumn. It supposed to print even stainless steel from wire, not like these days 3D- sinters does metallic 3D-models only from metal powder.
Another problem is for the boat project, that for one hour driving with full power would be needed 74V 500Ah battery capacitance if I will use my chosen brushless DC motors where into have to scale the propeller smaller then could use just some hard plastic to print those.
Here's the original one
