Wooden Beast KNex coaster cars

thingiverse

This project is designed specifically for the micro Knex roller coaster, aiming to replace the subpar plastic car covers that come with the sets. With minimal adjustments, you can customize the front to suit your preferences. The measurements are meticulously taken in millimeters to ensure a precise fit on the wheel base. To expedite the build process, I incorporated elements from two other projects that proved to be excellent resources, fitting seamlessly into place. If you decide to print this design, remember to drill holes into the base for secure wheel mounting. Following further refinements with a digital caliper, I have updated the file to accommodate a 4-car setup, utilizing custom spacers and rubber bands for optimal connection. Additionally, an extended groove has been added to securely hold the chain lift finger in place. While this feature is not essential, it can be easily modified to match the length of the adjacent side by clipping it accordingly.
