Gravitrax magnetic ball remove

thingiverse

Here's a ball retriever for Gravitrax. It lets you take out balls from the launcher as well as pick them up when they roll under the transparent plates. The grip has been fine-tuned to fit through the tunnels. The magnet is strong enough to grab multiple balls at once (I've tested it and so far, I can handle up to 9 balls). This bracket makes it easy to position the retriever on an empty slot and even stores up to six balls.
