My 5th 3D printed marble machine.
A viewer of one of my other machines had suggested I try using Blacklight LED's and Neon colored filament. I was able to also find glow in the dark marbles (having always used steel ball bearings, i have found that I am not a fan of glass marbles. They have too many defects (not round enough).
To make it more visually appealing I decided to make all moving parts a different color.
This was designed with Fusion 360, and printed with a Bambu X1-C.
I have been making one of these each winter since teaching myself how to use 3D cad and how to 3D print.
