This parametric Brio Straight Track offers maximum flexibility for anyone who wants to expand or customize their wooden train system.
The model is fully parametric and can be configured directly in the browser or in the MakerWorld app. The generated STL files are automatically adjusted to the selected values.

🔧 Features & Functions

Compatibility

  • 100% compatible with Brio and all common wooden railway systems
  • Precise, double-sided profile → part can be rotated or flipped as desired

Parametric Adjustment

  • Create straight tracks without incline
  • Or tracks with incline – ideal for ramps or bridges
  • All dimensions freely adjustable within safe limits

📏 Parameters & Limits

Straight Track (without incline)

  • Length: 52 mm – 248 mm

Straight Track (with incline)

  • Length: 52 mm – 248 mm
  • Maximum height (incline): up to 60 mm
  • The model automatically checks if the incline angle is possible
    → If the incline would be too steep for the chosen length, the track will automatically extend until the incline is realistically printable.

Bridge Mode

  • With maximum incline, two identical parts can be combined to form a complete bridge:
    1️⃣ Ascent
    2️⃣ Descent
  • Since the profile is identical on both sides, the same track can simply be used mirrored.

🧱 Construction & Geometry

  • Double-sided Brio profile for maximum compatibility
  • Consistently uniform connection heights
  • Defined incline geometry for clean printability
  • Stable internal core that reduces warping during printing
  • Optional ramp surfaces run cleanly from profile to profile

🖨️ Print Recommendations

  • Support recommended for tracks with incline
  • Layer Height: 0.2 mm recommended
  • Infill: 15–25% Gyroid or Grid
  • Material: PLA, PETG or Wood Filament
  • Orientation: Flat on bottom, or side surface

🧒 Safety Notice

The component is stable with normal settings and suitable for children's hands, however:
The model is not a certified toy. Use at your own risk.

💡 Note on Parametrics

The STL is automatically generated after entering the following parameters:

  • Track Length
  • Activate Incline (Yes: value for height increase >0)
  • Incline Height (0–60 mm)

Thanks to the double-sided profile geometry, you can create:

  • simple straight sections,
  • gentle ramps,
  • steep bridges,
  • or complete ascents/descents
    without needing any additional models.

✨ Happy building!
