Gravitrax Compatible "Follow Me" Marble Multiplier

thingiverse

This marble streamer is a new addition to the Gravitrax game, allowing more marbles to run along the track at once. The idea for this model came after using stock "Volcano" and "Splash" tiles, which only allowed three marbles to go in different directions. Instead, I wanted a snake-like stream of marbles on the same track. To split them up later, I can use my Temple of Chaos tile. This marble streamer is non-blocking, meaning triggering marbles just run through it and continue after triggering it. It doesn't stop like "Volcano" or "Splash" tiles do. Even after triggering the Follow Me tile once, other marbles can run through without being blocked. Check out my Post Printing section if you want to see this in action! I designed the marble tower so that it has its own sections, but it's compatible with transparent tube sections from the Gravitrax Lift expansion. If you have the Lift expansion, you can connect tubes to other rail sections and have marbles fall into the tower, filling it up for the passage of the triggering marble. When printing this model, pay attention to these things: The bottom part of the marble tower should fit tightly with the tile it's mounted on. If it's loose, add a layer of tape or glue it in place. The latch that swings free the marbles needs to turn freely. Be sure to sand the top face of the tile and the bottom face of the latch, as well as circular holes it swings into, to remove friction. The guide that keeps exiting marbles on track needs to be firmly fixed to the tile. Follow the same instructions as for the bottom part of the tower to secure it in place. If you make this model, I'd love to see pics of your creations! **Note:** I'm not associated with Ravensburger or Gravitrax; this design is just compatible with the Gravitrax system that provides functionality stock parts don't. I do this for fun, but if my projects help enhance your Gravitrax experience, consider tipping me - it would really mean a lot!
