Make sure you have an Arduino or equivalent microprocessor, big enough sheets of 3mm material to cut the design from and plenty of wires and M3 10 screws and nuts to assemble all the parts.
- As a rotor we wil use a 3D print of your own design, or this Microfuge 8 Place Rotor

- Hard drive motors also speed up to about 7400 RPM, but if you choose to use this you will have to change the entire design
