Modular, Snap-Together Marble Run

A modular marble run system that works on any 3D printer. No AMS, no supports. Print the pieces you need and snap them together to build towers, tracks, and full runs.

Each piece is designed to be reused, restacked, and rearranged. Start small and expand the system over time, adding more towers, longer tracks, and new layouts as you go.

New to the system? The Complete Starter Kit has everything for the example shown. Just add a 10mm marble or steel ball bearing.

Pieces in the system:

Towers

Base plate
Tower segment
Inline connector
Track bracket

Tracks

Straight track
90° turn
180° turn
Ramp

Endpoints

Start funnel
Finish bowl

Details
