Train bridge toy

A fully functional, 3D-printable Modular Educational Bridge Set designed to teach structural engineering through hands-on play. This project demonstrates how static loads are transferred from the bridge deck to the ground through a series of interconnected structural components.

Features:

Structural Engineering STEM Kit: Designed as a teaching tool to help children learn the fundamental elements of a structure and how they support one another.


Modular Assembly: Features a "Lego-like" snap-fit system where every part is designed to connect seamlessly without interfering with other components.


3D Optimized Precision: The model includes a 0.15mm offset on all female connection points to ensure a perfect mechanical fit directly from the printer.


Verified Durability: Validated through Autodesk Fusion static stress simulations, ensuring the design is "Very Strong" with a high safety factor for reliable play.


Kinetic Variety: Includes various structural types such as
