Märklin stang kobling
thingiverse
Märklin adapter coupling. It is used to connect two carts together in the Märklin model train setup securely. Inspired by a similar device that unfortunately does not fit perfectly, this one is longer and offers a more precise solution. It will be thoroughly tested in real life over the next few weeks to ensure its effectiveness. *Edit: Version 3 has additional material behind the lock tab for easier 3D printing with a coarse hotend/extruder.
