The marbles slide down the chute where they pick up speed and exit fast into a big funnel. They roll around for a while until losing all the speed and drop down into the hole.
This module has two versions. One requires supports and the other one can be printed without supports. Print whichever version you prefer.
The module was designed in a way that it is printed laying on its side. That is because the funnel can stay very smooth and still be printed at 0.3mm. We do not recommend printing it in upright position.
You are buying digital STL file available to download immediately after purchasing. You will need a 3D printer (13*13*13cm) to print it. This module fits on all of our marble machines.
The files are in .3mf format. Upon request we can send you STL format. Read here why.
