This is an innovative design for the Esso Design Challenge on my Mini Factory, featuring a roller coaster that can be built using 250ml drinking cans in combination with 3D printing. For a working view, see the YouTube link: https://youtu.be/6ZWX5sUdo2A. Start by printing the track and can connectors. Build everything together, then attach 3mm filament to the rail, which will click into place. The rail is connected with adjustable parts that ensure proper alignment. The cars can be joined together using car-to-car connectors, placed on top of bearings that allow for smooth movement along the track. I used M5 and M8 bolts, nuts, and spacer rings for various connections, including 608zz bearings. For optimal print quality and fit, use a .35 nozzle with a 2-layer height. The track is designed to be flexible, allowing for twists and turns. Track part 3 can be cut to the desired length, ensuring a seamless connection between parts. All components slide together with minimal pressure, requiring only slight sanding to achieve a snug fit. I've included pictures to help you visualize the assembly process. Enjoy building your own roller coaster using this design.
