Train tracks - Ikea

This 3D-printable modular train track system is designed to be fully compatible with IKEA wooden train tracks, while also functioning perfectly as a standalone track set. The design allows builders to create engaging layouts that rise up to three levels high, adding vertical play and dynamic routing possibilities to any train setup.

A key feature of this system is the mechanical locking connection between the tracks and the bridge support elements. This locking mechanism significantly increases the overall strength and stability of the construction, making elevated track sections sturdy and reliable during play.

The set includes a variety of track pieces, such as:
- Straight tracks
- Curved tracks
- Intersection tracks
- Elevation tracks that smoothly raise the train to the next level

All components are optimized for PLA printing and can be produced on standard 3D printers. For enhanced strength and durability, 3–4 wall loops are recommended, especially for elevated sectio
