Note: This is an expansion to the Roll Hexfinity System. You will need to also print the Roll Hexfinity Starter Pack. I also recommend printing the Split and Merge Pack for use with The X Files Pack.

Add mesmerizing new dynamics to your Roll Hexfinity system with The X Files expansion pack! This set introduces two new X-shaped bricks that allow balls to criss-cross each other in mid-roll, unlocking stunning, intertwined pathways and adding even more creative possibilities to your modular maze designs.

Why Add X Bricks?

Sometimes a simple roll isn't enough—you want motion that feels alive. The X bricks create visually striking intersections where balls cross paths and interact, adding delightful unpredictability and motion to your builds. Watching balls weave through each other brings a whole new level of excitement, energy, and complexity to your layouts.

What’s Included:

• X1 Brick: Features two input paths angled 120° apart. Great for broader, sweeping crossings.
• X2 Brick: Features two input paths angled 60° apart. Perfect for tighter, high-energy intersections.

The difference is subtle at first. The X1 brick works easiest with the split and merge bricks since their exists and entrances are also 120° apart. The X2 brick, though, can also be perfect when you want some tightly intertwined paths.

Both bricks are standard 21mm "brick" height with a 7mm downslope—matching the design of all non-flat Roll Hexfinity bricks. The downslope ensures that even when paths directly intersect, the balls naturally resolve their collisions through physics, keeping your maze flowing smoothly.

Recommended Pairings:

The X Bricks work best when combined with elements from the Split and Merge Expansion Pack, allowing you to split balls onto multiple paths before they cross over and interact at an X junction. Creative use of splits, merges, and X intersections can create dazzling, layered designs that feel alive and spontaneous.

What's Next?

The X Files is part of the continuing expansion of the Roll Hexfinity system. With this release, your ability to create intricate, criss-crossing ball mazes becomes even stronger—and there’s still more to come! Advanced modular systems like Roll Hexfinity Air and Roll Hexfinity Bridges are in development, along with the upcoming Store Hexfinity storage platform and more ways to integrate with Gridfinity through Hexfinity adapters.

Full specifications and model files for Roll Hexfinity are available on my GitHub repo, so you can build, customize, and expand however you like.
