Toroidal propellers are the hot item right now! Quiet and efficient, toroidal propellers have great potential with a variety of applications. Why not have some fun with them?!

This simple, lightweight, flying disc has a lot of promise. Currently sized to fit on the build plate of a Prusa Mini. This results in a disc with roughly a 178mm / 7in diameter.

Since propellers are directional, there are both right and left handed versions available. Each version then has the option of a flat edge (has a very small fillet) or a filleted edge (4.5mm fillet).

Test prints done using PLA with a 0.25mm layer height.
