Skill Level: Beginner friendly—no prior 3D printing, electronics, or model railroading experience required.
Ideal Event Types: Train enthusiast groups, hobbyist & maker sessions, youth STEAM clubs, library maker spaces,, and adult tech literacy sessions.
Max Attendance: up to 30 participants
First 15–30 Mins – Tech Intro & Discussion
An engaging opening discussion on the history, engineering, and mechanics of train locomotives, alongside an overview of how custom 3D-printed parts come together in scale models.
Next 45 Mins – Guided Hands-On Build
Step-by-step guided assembly where attendees assemble the battery power system, motor drive, and internal electronics before mounting them inside their custom 3D-printed train chassis.
Final 15 Mins – Testing, Customization & Wrap-Up
Testing motor operation and speed, troubleshooting mechanical alignment, and packaging up the completed train to take home.
