An extendable track for your marble run compatible with Gravitrax.
Depending on the height, the original rails were always a little too short.
With this track you can adjust the length variably.
Print instructions:
You can print it without support, there is a small integrated brim, which you can easily remove with a cutter knife after printing.
Parts:
The rails come in a long and short version and there is a connector, so you can extend the rail as long as you want. You need to print at least two outer rail parts and one middle part.
Possible Lenghts:
Long Version: 275mm - 430mm
Remix Information & Changes:
The track is based on the model from Hubert76. Großes Danke für die Idee!
- Requires less material thanks to holes in the design
- The track support so that the ball does not fly off track after a corner was added
- It now prints without support and only a small integrated brim must be removed
- The rails now sit a little tighter
