optimized spiral for marble machine

thingiverse

I've created a new spiral design with a gentler slope and only one track because it performed better for me. This spiral was specifically designed for 12mm marbles - essentially, stainless steel balls sourced from car ball bearings. In my situation, I opted for the counterclockwise version of the spiral after making some minor adjustments to the machine itself, and it worked flawlessly. That being said, the original marble machine might necessitate the clockwise version, but since I didn't test this function, I can only offer a mirrored version of the counterclockwise design. Kudos to Tulio for their excellent work, and many thanks for making this machine available.
