You are buying STL files available immediately after purchasing. You will need a 3D printer to print with a minimum bed size of 200x200x185mm.
Price is for the base machine only, you also need to add a minimum of 3 modules to the cart, unless you already have them. All of the modules on our website are interchangeable between all of the machines.
I also sell 3D Printed fully assembled version here.
Overwhelmed and need a distraction from your busy workday? This 3D printed marble machine is exactly what you’re looking for!
This marble machine comes in many different interchangeable models so you will never get bored of watching the marbles go around the track as there are always new paths and patterns for them to travel.
Now you can give your mind a break from your hectic life and take a couple of minutes to just relax.
This 3D printed marble machine run also makes the perfect gift to give to your family or friends.
You are NOT allowed to resell this in digital or 3D printed versions.

Assembly
Extensive assembly instructions can be found here.
I loved the modular concept and promptly purchased the Two Wheeler and three modules. The price was fair and I'll be buying more in the future, and recommending it to other 3D print hobbyists.
The Test Print was too tight with PrusaSlicer, but perfect on my CR10s Pro with Simplify3D so that's the way I went.
I've enjoyed printing it and assembling it and playing with it, but it's been a challenge. I found that throughout the model, tolerances were too tight. The printed pins fit neither the wheels nor the supports; rather than sand the pins down that much, I simply drilled out the holes. Likewise, the M3 bolts and nuts and the FlipFlop didn't fit; I had to drill out every hole. I cracked two parts while forcing the nuts into their spots and wound up melting the rest in with my soldering iron. The Split didn't work and had to be reshaped. Several parts were too tight for 1/4" ball bearings and would be impassible for the 9/32" bearings in the hardware kit. They took a lot of work to reshape.
I'd guess that this was something about my printer, but my previous project, Thing #4002445 fit together beautifully (with the exception of the axles). Why should this one be so much different? I plan to redo some parts using PrusaSlicer to see if that makes a difference.
Overall, this design is a work in progress that will continue to improve. I consider it well worth the price and the effort of printing and assembly.
amazing stuff!!
Ich bin sehr zufrieden mit der Marble Machine und freue mich schon auf neue Module, die vielleicht schon bald angeboten werden.
Die Qualität ist sehr gut und alles ist sehr passgenau.
Ich habe die Maschine schon in unserem Druckerforum weiterempfohlen.
Die Resonanz war sehr positiv..
Vielen Dank für die schöne Idee und die perfekte Umsetzung.
easy to print and fantastic final result
Goede afwerking mooi passend allemaal. Knap designed.
