Build Info:

Parts can be printed from PLA.
Higher grade magnets will produce more power (I used N52 grade).
Coils can fit 350 turns of 0.4mm enamelled copper wire, but make sure the coils aren't too large for the template.
All coil turn direction must be the same for all coils.
Magnets must be mounted in alternating polarities.
Make sure rotor magnets align when on the shaft.
Magnets must be alternating poles, see video for reference.
