GraviTrax compatible pendulum starter

thingiverse

The pendulum starter is not a standard part of the Ravensburger GraviTrax system.\r\n\r\nThe concept is that you can place one ball on top of the pendulum, and when another ball hits its bottom end, the ball on top will fall onto the track. The pendulum's top end fits perfectly into the original GraviTrax part for the swirl or target hexagons.\r\n\r\nTo assemble the pendulum starter, you'll need a metal pin (about 2.5cm long and less than 2.8mm thick) to serve as its axle.\r\n\r\nMy son and I designed this add-on after creating numerous extra bridge piers for GraviTrax. We needed a way to easily access the upper tracks, so we came up with the idea of a pendulum starter.\r\n\r\nYou can find links to my other compatible GraviTrax parts below: Tracks - https://www.thingiverse.com/thing:2738473 Curves, Straights, and Joins - https://www.thingiverse.com/thing:2738494 Magnetic cannon - https://www.thingiverse.com/thing:2738601 Bridge piers - https://www.thingiverse.com/thing:2738439
