This is a simple and easy to print Tetrahedron-ish gyro toy. It prints in 1 piece with full supports. Once free it should spin effortlessly easily/fast.
when printed, insert something that can be twisted around (I used a small pick) into the center hole to break up the supports before trying to spin it. I printed with minimal supports with no roof or floor.
