Bucket Lift | Marble Machine STL

By subscribing you will receive download links in your email and further emails when we release new marble machines & modules.

You can also purchase Hardware Kit, so you don't have to worry about marbles, motors, etc...


You will need a 3D printer to print with a minimum bed size of 180x180x180mm. Yes, it can be printed on Prusa Mini by disabling the skirt.

G-codes for Prusa printers are also provided in the files!


All of the modules on our website are interchangeable between all of the machines.

You are getting two versions. The first is motorized and the second is hand-cranked. You can print just one of them or both if you would like. For the motorized version, you will need a hardware kit and for the hand-cranked version, you will only need the marbles. The kids absolutely love the hand-cranked version, since it is more intractable!

We also sell Fully Assembled Bucket Lift.

You are NOT allowed to resell this in digital or 3D printed versions.

    Printed on: Prusa MK3s+
    Filaments used: PLA (eryone)

    5 starts for making this free. Only problem I had was that the chain does need to be tight or it gets caught where the marbles enter. But taking the top off after putting one on is impossible. The layer lines act as velcro. I'd prefer a mechanical tightening system that used a screw/nut. I can see you want all plastic.. but I think some judicous metal will make the models last much longer. https://youtube.com/shorts/gey4UPcToms (your form won't accept this link)

    Quite a conversation piece, visitors love it! Keeps my father amused for hours on end sitting in the sun. Now he wants me to print more

    Took a little bit of leg work on my part to get it all setup correctly, but now it works great!
