Rollercoaster

cults3d

This is a design for the Esso Design Challenge on my Mini Factory, where you can build a working rollercoaster using 250ml drinking cans in combination with 3D printing. To get started, watch this video on YouTube: https://youtu.be/6ZWX5sUdo2A. Once you've seen how it works, begin printing the track and connectors. Build everything together, then use a 3mm filament to create the rail parts that click into place. The rail is designed with adjustable connections that can be adjusted in any direction. Cars can be connected to each other using car-to-car connectors, which fit onto bearings at the top of the track. Leave some space between them so they can move freely as you ride down the track. I used M5 and M8 bold and nuts, along with spacer rings for connections and bearings (608zz). For best results, print with a 0.35 nozzle and 2-layer height. You can choose from different track lengths, including part 3, which is a flexible section that allows you to twist the track as needed. This part can also be cut to size if necessary. The track parts fit together snugly with a little pressure, but you may need to sand them down slightly for a secure connection. Check out the pictures I've included to see how everything comes together. Have fun printing and building your own rollercoaster!
