Lego Propeller
thingiverse
This is a Lego-compatible propeller featuring 5 durable blades designed for direct integration with a Lego "M-Motor" without the need for gearing. I have successfully utilized it on numerous Lego RC boats. Print Settings Printer: Rafts: Doesn't matter, as you can print without them. Supports: Yes Resolution: A higher resolution is recommended to minimize drag and optimize performance. Infill: You can choose your preferred infill pattern for the center section; it won't affect the blades, which will remain solid in any case.
