Hand Powered Helicopter Propeller Toy

A simple, fun outdoor toy — spin the rod between your hands and launch the propeller into the air! Scalable to your liking; the standard 6mm rod hole fits over common driver bits.

PETG is recommended for the propeller blades for extra flexibility and durability; PLA works well for the rod.
