Marbleworks Compatible Wiggly Cycloid

thingiverse

This is a part of a parent collection of many different marble tracks compatible with Marbleworks Grand Prix marble set. See remix source for larger collection of marble tracks. Here we have a rare double loopy-zig-zag design. Very rare in the wild. Luckily the supports don't bite much. Overall a nice design that combines curves with sharp turns in the Z-section in the middle. This piece is sqrt(3) length compared to normal tower pieces, meaning you can put two equilateral triangles back to back as a diamond and then put the model across the longer side of the diamond. Here's the math used to generate the shape: ``` x(t) = t - sin 4t y(t) = cos 3t ```
