Marble run - extendable & flexible rails/tracks (Gravitrax compatible)

Looking for curves and curved slopes? 

Looking for the Bridges/Plates/Grid system from the photos?

08.02.2023: Added a Flexible variant with 2-* parts. Simply print as many outer and inner rail parts. 

08.02.2023: Added 4-7 Tiles variant.

•  
• WIP: More sizes will follow
• Tight connectors to have a stable connection to tiles
• The connectors have a modified shape in order to have a clean and smooth marble transition without hills even with sloping construction. 
• Thanks to the flexibility, it is even possible to create curves

Print
Print 2x Connector 1xMiddle. 

Assemble

Push the Connector parts in the middle part. This will require some force because there is a tiny hook to keep all parts together. After the first ~10 mm it will “click” and everything will move smoothly.

Note: 
I am in no way affiliated with Ravensburger or Gravitrax. All parts are my own creations and serve a purpose or function that the original parts can not. However, they are compatible with most Gravitrax components or alternative Gravitrax-like marble run models. I do this purely as a hobby with no intention of making a profit.
