Marbleworks Compatible Twist-tie

thingiverse

This is part of a parent collection that features multiple marble tracks compatible with Marbleworks Grand Prix marble set. Check the remix source for an expanded collection of marble tracks. The design offers some twisty adventures where parts may collide at the center junction, which poses a level of risk. The twist-tie has marbles approaching from opposite directions, but world-shattering events are unlikely as walls cover their escape paths fairly well. For those interested in the mathematical aspects, the paths are defined by: ``` x(t) = sin(2t) y(t) = sin(t) cos(7t) ```
