I just finished printing and assembling this rotating marble run. Challenging but fun, and I learned a lot. I downloaded the 3D model from Bambu Lab’s #Makerworld and ordered the electric parts. After creating this video I lightly sanded some areas where the steel marbles tended to stick and now it works better.
There is an LED strip inside the center spiral. Printed on a Bambu Lab A1 using their filaments. #3Dprinting
Here’s the model:

@DavidBFox That is SO COOL. How much did it cost to build $$?
@worldsendless the model itself was a free download. And it doesn’t use very much filament (even with a few failed prints)
@worldsendless the kit of non printable supplies was under $70, plus shipping but since I ordered additional filament spools my overall order was high enough for free shipping. Some of the parts came as pairs so I could order a few more items and have enough to print a second one. Ordering info is at the link.
