Lego Duplo Train Car/Wagon (Snap Together)

thingiverse

This remix brings together five distinct projects: **Lego Duplo Wagon Passengers** by fsa, **Duplo Compatible Fully Printable Train Wagon** by nirgal, **Duplo Train Wheels** by YorickDesign, **Duplo 4 Wheel Cart 2x6 Brick** by Non-ICE, and **Yet Another Duplo Brick Generator** by badger. Each object was modified in TinkerCad to incorporate Duplo-compatible connectors and additional modifications for size and strength. The result is a more robust train car that can be printed in PLA, fully snap together, and withstand rougher play from my 3.5-year-old son. I took the cabin and roof from **Lego Duplo Wagon Passengers** and shortened them to fit onto the **Duplo Compatible Fully Printable Train Wagon**. I then created a 4x1 block using **Yet Another Duplo Brick Generator** and attached it to the cabin in TinkerCad, allowing it to snap onto the platform. I also modified the roof to thicken it and add a row of Duplo-compatible connectors from the platform of **Duplo Compatible Fully Printable Train Wagon**. The platform of the train wagon was modified to include a socket for the hook connector post. I extended the post from the frame to lock into the socket, ensuring strength when my son pushes or pulls the trains aggressively. The frame was elongated to accommodate the hook post and additional horizontal support beams were added: one along an axle and another vertically to stabilize the hook post. I then modified and attached the wheel connectors from **Duplo 4 Wheel Cart 2x6 Brick** to fit the wheels from **Duplo Train Wheels**, which are included in this print but remain unmodified. An Alternate Roof model is also provided, a shortened version of the one from **Lego Duplo Wagon Passengers** by fsa, allowing you to print the train car without Duplo-compatible connectors if preferred.
