I don't think I've ever encountered such badly invited 3d models that you have to pay for.
I have wasted a lot of time, electricity and filament to find that the model has gaps of several millimeters, specific parts don't come together, mounts break from looking.
Waste of money, there are nicer toys to buy and print than this!
The out of marble’s hardware kit was just the thing to finish off the Big Wheel marble run. It’s been a hit with not only the grandkids but everyone that’s seen it!
Very well designed, great instructions and everything works smoothly.
This marble run is very fun and easy to print!
