The 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 intractable!

 

We also sell Fully Assembled Stairs.


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

    Printed on: Prusa MK3S and Tevo Black Widow
    Filaments used: Spool3d PLA - Marble, Black, Purple

    Printed just like all the other modules and machines
    Perfect
    No issues no errors and only the slightest touch ups (sanding /trimming loose strands (ie crossing perimeters, tight corners)
    This one was not 100% perfect the tipper/re-director was a bit off. All it required was a small dab of hot glue for a weight return balance. About as easy as it could get:
    Buy it, download it, print it and play.
    did the motorized version and just finishing the manual one (for the kids) I will put that one on a hardwood base for weight and display so as to make it easier for turning the crank for the grand kids (they enjoy a bit of more interaction with the model than just pushing a button)
    Now for the Tower Machine!

    Pretty cool, but...

    It is a masterpiece, but it doesn't come in STL, and they are all bunched together. I used a converter and it rearranged them weird. I figured out I could add a program into Cura that splits all of the combined parts. That way if there was a failed print, I don't have to wait another 20 HOURS. As mentioned previously, it was hard to get the stairs to slide easily. I think in the next one I am going to make one of the stair pieces 1% smaller.. BTW, I sent an email to them asking if I could get a STL version, no response, and they have always responded in the past.

    Filaments used: Prusament PLA Viva La Bronze & Galaxy Black. Also black prusament PETG for few parts
    Great idea, though model could be tuned better for easier printing

    First I do love the stairs idea and an option for manual control (I got hw pack too, but I thin for kids manual is more fun). I think only for such idea is worth paying some amount.

    Though I am struggling to get stairs loose even after sanding (I did calibration print and got fine results from first try) or applying oil so it pulls down with gravity. Instead I would suggest to attach stairs to large shaft so it not only gets pulled up but also pushed down.

    I was also struggling to print one small part where you would put toothpick which after 3 failed prints from PLA I've printed with PETG and then it worked. Similarly handle softer from PETG it just worked without heatgun. I think it's possible to design these parts smarter so they are more print-friendly.

    Finally, I know you can get some module parts for free, but it would make sense that at leas one is included when you buy STL (e.g. these which you already distribute free in prusaprinters or thingiverse)
