Intricate Marble Run Machines Made Out of Cardboard
Marble enthusiast B-dama Friend creates intricate multilevel marble run machines that are completely made out of cardboard. The Marble Run Machine 37 Spin-off" is one such machine. It uses parts from past machines to make it taller than any run built before.
(translated) I broke the 37th work and finished it as another work! Run 4 courses without crossing red, yellow, blue and green marbles (49 in total)! Even though it uses the same mechanism as the previous work, I think it became a marble coaster with a completely different impression.
In addition to making these runs, Friend also records accompanying videos showing how the run was built.
(translated) This is a channel dedicated to marble coasters (Mable Run Machine)! Not only the work but also how to make it is introduced. ...
Here's the original Marble Run Machine 27.
