Michael Henriksen’s Hand-Cranked Marble Machine

Michael Henriksen’s laser-cut marble machine sends 5mm ball bearings rolling through a spiraling track. You can adapt the machine to work either left or right handed, and works whether you crank it clockwise or counter-clockwise. He sells kits on his online store.

  1. I purchased one and had fun assembling it.
    Very popular with the family and visitors, a great talking point.
    I will be watching Michael’s website for more interesting items.
