Wintergatan is a Maker, a Youtuber and an experimental Musician who decided to share his passion with the community and decided to build this extraordinary musical instrument, a very complex Marble Machine, it is the second version he is building, a much more elaborate version 2.0 and that corrected the defects of the first version, which was mostly made of wood.
To build this machine, he used Design and Simulation with various existing Cad-Cam applications, he used the CNC milling, 3D printing and classic processing techniques used for making and in order to carry out the realization this dream is asking for help from the internet community, enjoying great success.
I share this example happened here on Blender Artists, because I hope Blender can soon become a useful tool for Makers like Wintergatan thanks to bridging the current gaps in precision modeling and CAD in general and expanding the simulation and animation of their projects.
the marble machine X is not yet complete, but in this video, its realization has reached such a point that it already shows all its fascinating potentials:
