Squished spiral for GraviTrax - so you can actually see the marble
Description
Squished Spiral - Gets rid of the unnecessary depth of the original by reducing the middle section from 46mm tall to 15mm tall (now it should line up with GraviTrax tiles as well as an added benefit). Since the height reduction reduced the wall thickness of the track, I also increased that thickness to give it a few other layers when printing. Next step will be to redesign this part right, by giving it a flat bottom with snap-in or glue-in rings, so the part prints as a shell with infill. Better than having to remove supports, and not much difference in filament used. The current open shell design is unsatisfactory as it either leaves a rough surface below due to the removal of support material, or if you print upside down then the track is not smooth. Also, the current design's built-in mounting ring is too thin and tends to get damaged when removing support material if you're not careful.
