This is a small modular marble track system built with 10 cm long track segments and an 8 mm steel ball (standard ball bearing size).

The parts are designed to stack freely, making it easy to build either a simple tower on two legs or one on 3 legs. 

The starter kit includes:

• 3 straight tracks
• 2 curved tracks
• 2 base elements
• 1 end base
• 1 starter funnel
• 4 spacers

All parts stack without clips or glue; more parts are planned to expand the system.
