Marbletrack - Spiral (Gravitrax compatible)

The spiral is modular. That means that there is a minimum set of required parts, and a few optional parts to increase the height, change the marble inlet, add stabilizer pillars etc. 

Marbles cannot fall out of the Spiral - no matter how fast they are. 

The base for the spiral is my elevation system. However, it fits into other  Base Tiles (e.g. JDO solution). (If requested, I might add a version that fits into the Gravitrax Base Tile as well)

The minimum set:

1. Base Tile 
2. Hex-Connector for the Basic Tile
3. Base
4. [Optional Extensions]
5. Head
6. Single Inlet  (A single Marble inlet - from any direction)

With “Crown”

The Crown uses the Base Tile as well and allows marbles from any direction simultaneously.
Moreover, you can attach Pillars from my elevation system to stabilize the tower, or attach additional balconies.

• Base Tile 

With “Crown Intermediate Inlet”

The Crown Inlet can be used to build giant spirals and run the balls in at different heights.

Print Instructions:

• Print all parts without any support!
• I use 0,2mm PLA at 200°C ( Better Overhang Performance on my Prusa Mk3S)
• Should work with other settings or layer heights as well

Assembly:

1. Push the Hex-Connector in the Base tile (Instructions)
2. (Optional) Push the Crown or Crown Intermediate Inlet in a Base Tile
3. Attach all elements together. Simply push them together in an angle of ~60°, then twist.

Note: 
I am in no way affiliated with Ravensburger or Gravitrax. All parts are my own (derived) 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.
