• With just over 1 kg of filament, we’ve created a simple yet functional 4WD race track—optimized in every aspect, from dimensions and internal voids to seamless assembly and secure snap‑fit joints (the snap‑fits are optional; if you’re aiming for higher speeds, you can add them as needed).
  While it does take some time to print, compared to other race tracks available online, this one delivers the shortest print time and lowest material usage—while maintaining the same overall dimensions and track length. If you’re looking to get hands‑on and experiment with your own designs, give it a try!

Designing and fine‑tuning these tracks isn’t easy—but if you’re a Topaz community member who appreciates the effort behind them, please consider lending a helping hand! 🙏
