Build it your way. This system is fully modular, so you can expand in any direction and create a run that’s completely your own. Twist and snap together your custom marble run.

This starter pack includes:

• Base plates
• 5 pillars
• 6 toppers
• 3 bridges
• STL, 3MF, and STP files with detailed instructions

All parts are beginner-friendly and easy to print (no supports needed, except bridges). If you can imagine it, you can build it—just grab a 1/2" marble (affiliate) and start creating.
