🎢 Modular Hex-Grid Marble Run | Support-Free Starter Kit 🟡🔵

Unleash your inner engineer! Build endless track combinations with this fully modular, 3D printable marble run system.

Designed around a clever hexagonal base grid, you can snap together custom layouts, build towering drops, and watch the gravity-defying fun. The best part? This is just the beginning! I am actively expanding this system based on YOUR feedback.

✨ System Features: • 🛑 Dovetail Hex-Grid: The yellow base plates slide together using satisfying dovetail joints to create a solid, unmoving foundation. • 🏗️ Stackable Towers: Easily adjust the height of your tracks by stacking the modular hex blocks. • ⚙️ Hardware Needed: Designed perfectly for 10mm (or smaller) stainless steel balls. You can easily grab these from the Bambu Lab Maker's Supply store (FA006) or use any standard 10mm bearings you have on hand!

🖨️ Slicing & Printing Tips: • Zero Supports Needed: The entire system is engineered to print 100% support-free! • Part Orientation: Most parts print flat, but make sure to lay the downward slide tracks on their side on the build plate for the best layer adhesion and a perfectly smooth rolling surface. • Scale: Print at exactly 100% scale to ensure the 10mm steel balls fit the tracks perfectly.

🚀 Updates are Coming! I want to build the ultimate marble run system. Got an idea for a crazy loop, a motorized lift, or a trampoline bounce piece? Leave a comment here or reach out on my socials with your suggestions for the next expansion pack!
