Bead bearing marble labyrinth ramp (mountain)

This is a ramp marble maze that's scaled down to work with a ball bearing. The one in the image is an earlier version that had too shallow of a gradient for the bearing to reach the bottom. My printer is having trouble printing the complexity of the enclosed version which should work just fine.

This maze ramp must be printed with a vetical resolution of exactly .3 mm or the bearing will get stuck/fall off at points.

Here's a flattened version of the labyrinth (based on Chartres Cathedral in France):

If you found this useful, it would bring me great joy to see your work - so be sure to share. :)

Or, better yet, please feel free to dump a bitcoin or two here (I'm trying to collect as many as I can before the apocalypse):

... include a note to the effect of "Hi 3E8, thanks for the holy maze thing... my life is infinitely better on account of it and please accept this small handful of bitcoins in gratitude".

You're welcome! (in advance) :D

Also, feel free to peruse my other submissions which are almost as varied as they are many:
