I was curious to see how big this would have to get to work with normal sized toy marbles. Turns out it had to get quite a bit bigger! All parts have been split to fit on a MK3 print bed.
All files were printed as thick and fast as I reliably could with the standard 0.4 nozzle on a Prusa MK3S. I used Prusament PETG with a layer height of 0.25mm and a print speed of 60-90mm/s. The only exception to this is Tripple Twister Top Part 2. This needs to be nice and smooth for the marbles to spin properly and I wouldn't use a layer height over 0.1mm even at this scale.
