342 RPM with 3D Prints 9v Battery Clips for Compass Magnet Motor

We are continuing to make minor improvements to the Compass Magnet Motor by using some 3D printed parts.
If you are patient to watch to near the end of the video you will see a 5 second interval slowed to 0.125 x slow motion and can count 28.5 turns.
This is nearly as fast as the motor has ever gone. Our hopes are to get up to 700 RPM by improving the alignment of axles and motor as well as the balance.
You will see it starts to wobble at higher speeds. Also to be considered are the harmonics of the vibration which make it shake a lot as it reaches top speed.
Stay tuned:)
