I updated my LEGO Duplo straight track model based on fan feedback 🚂🖨️
Improved fit, tolerances and overall connection quality.
In the video you can see multiple test versions before the final improved design 🔧
Your comments really help improve the models.
The new version is now available on MakerWorld 👌
