Roll Hexfinity Spirals - Elegant, Stackable Paths

Sometimes your build calls for maximum drop in minimum space. Other times, you just want to create a visually stunning corkscrew tower for the pure joy of it. Either way, Hexfinity Spirals let you stack height fast—without needing 6+ bricks just to get the ball to ground level.

Each spiral piece is designed using the Hexfinity Air engineering style—open, lightweight, and highly printable, while remaining strong. The ball path is always visible through the mesh pattern (borrowed from Hexfinity Air Pillars), so you can watch your marbles rip through the spiral in style.

What’s Included

Core Spiral Segments:

• Six 42mm stackable spiral bricks, each with a different 60° rotational offset (0°, 60°, 120°, 180°, 240°, 300°)

  → Choose your start and end angle, then stack as high as you like

• One 21mm spiral brick add 3HU (height units) without altering your rotation. 

Entrances:

• 14mm (2 HU) entrance brick (standard)
• 21mm (3 HU) entrance brick (standard)
• 21mm entrance brick with Atomic Hexfinity connection for added modular locking

Exits:

• 14mm (2 HU) exit brick
• 21mm (3 HU) exit brick

Bonus:

• All of the above in both left-handed and right-handed spirals, so you can build mirrored layouts and symmetrical towers.

Highlights

• Stackable: Designed to make spirals as high as you want!
• Fast vertical drops: Drop 6+ HU in a single hex footprint
• Minimal parts, max effect: Far fewer bricks than traditional stacked runs
• Atomic-compatible: Use the Atomic entrance to secure your spiral tower into larger builds
• Mesh-based aesthetic: Strong, lightweight, and lets you see the action
• Choose your spin: Left and right-hand versions available

How it Works

• Entrance & Exit: Each spiral needs 1 entrance (top) and 1 exit brick (bottom)
• 42mm or 21mm Stacking Spirals: Add as many 42mm or 21mm stacking spiral bricks as you want. The sky is the limit!

Print Troubleshooting

If a print fails, start here:

• Wash your build plate. Oils from your fingers are the number one cause of failed Hexfinity prints. Wash the plate thoroughly with soap and water, rinse well, and make sure it’s completely dry before printing.
• Use a textured build plate. Smooth plates don’t grip Hexfinity bases as well and can lead to early lifting.
• Enable outside brims. If adhesion issues persist, turn on outside brims for extra stability.
• Reprint only what fails. When printing multiple parts, it’s common for just one to misprint. In the Bambu Handy app, you can cancel that individual part, let the rest finish, and then reprint only the one that failed.

Following these steps solves nearly every common print issue with Hexfinity and Atomic RollHexfinity parts. If you’re still having trouble, leave a comment — I’ll do my best to help.
