Cleaver Propeller

Human: Propellers Pitch is Around 24-29 inch in 14.5 inch Diameter. This propeller was 3D-scanned from a 17-foot long, two-seater offshore racing boat that reached speeds above 80 knots. My sister competed in this class when I was younger, and I've only had these types of boats for fun and hobbies since then. I've missed that hobby, but I'm now working on an electric speedboat project that charges its batteries from natural power sources at sea. I'd like to challenge someone to create a left-handed version of this propeller with the same structure and measurements. This would allow me to use two identical propellers in side-by-side motors for my electric speedboat project. I don't have experience with 3D modeling software, so I'm asking for help. In return, I'll post updates and information about the project on a public platform. Creating an exact mirror image of this propeller would require a metallic printer, which is something I've been researching through Prentashop, a Finnish company that specializes in 3D metal printing design. Their printers can create stainless steel objects from wire, unlike current 3D sintering methods that use metal powder. Another challenge for the boat project is determining the battery capacity needed to drive it at full power for one hour. With my chosen brushless DC motors, I'd need a 74V, 500Ah battery pack, which would require scaling down the propeller size and using harder plastics for printing purposes.
