Marble run Rails/Curves | Kugelbahn Schienen/Kurven (Gravitrax kompatibel)

Looking for straight extendable rails?

This set/work is still in progress. 

• The connector is very tight to get a stable connection between tiles and rails
• Most rails have walls to  work even with high-speed marbles
• Easily printable - with no, or a minimum of support
• There are
  • Straight rails 
  • Curved rails
  • Slope rails
  • … and combinations

Let me know if you miss any length/curve

Naming scheme:
 

<Length>_<Curve>_<Height>

Length: The amount of tiles to get from A-B
Curve: Angle in Degree (for slopes :  “+”: Curve to the right. “-”:Curve to the left)
Height: 10mm is the equivalent of a big height stone. Often slopes work for a range.

Example:
2T_-120D_5-15mm

A Curve to the left for 120° over 2 tiles. It is a slope that works best for a height difference between 5 and 15mm 

Printing:
I use Organic (Tree) Supports for slopes and the tiny bridge at the connectors

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.
