Modification of the STL model of the impeller for 3D printing (PETG)

There is a ready STL model of a two-blade propeller for a jet ski SUP board. The geometry of the hub and the seat for the shaft are completely satisfactory, they do not need to be changed.

What needs to be done:

“Cut off” the old 2 blades from the existing hub.
Design 3 new blades from scratch.
The radial gap between the edge of the blades and the inner wall of the housing (nozzle) must be strictly 1.5 mm.

Technical data for calculating angles and pitch:

Motor: Brushless, KV\ 200 (diameter about 50 mm).
Power supply: 42 V battery (BMS 60 A).
Controller: VESC 75200 V2.
The model must be optimized for FDM printing with PETG plastic (strong fillets at the junctions of the blades to the hub).

Good day!

I am ready to make improvements to your STL model. I will carefully remove the existing blades, design new 3-blade ones while preserving the geometry of the hub and mounting area, and I will also take into account the specified radial clearance of 1.5 mm.

During modeling, I will pay attention to the strength of the structure for FDM printing with PETG: I will add smooth fillets at the junctions of the blades to the hub and prepare the model for high-quality printing.

I am ready to discuss the project details and start working immediately after receiving the original STL model.
