Stairs | Marble Machine STL

Files were just updated on 24th of December and are now better than ever! Happy 3D printing!

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


You are buying digital STL files available immediately for download and 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!


You get two base machines, you also need to add a minimum of 1 module to the cart, unless you already have them. All of the modules on our website are interchangeable between all of the machines. You can also get a free marble machine module here.


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 interactable!


We also sell Fully Assembled Stairs.

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