Atomic Hexfinity Bridges

New: Atomic Hexfinity Curve Bridges are the perfect pairing. With both curved and straight bridges, anything is possible!

Atomic Hexfinity Bridges – Bridge the Gap!

Need to cross a gap? Build an overhead path? Or let two marble paths criss-cross without collision?

Atomic Hexfinity Bridges give you the structural reach you’ve been waiting for.

These lightweight, modular bridge pieces extend your Roll Hexfinity or Atomic Hexfinity builds with clean, elegant spans—letting you route ball paths over, under, and through your builds like never before.

Fun with stop-motion. [Bridges not actually stretchy nor bendy ;)]

What’s Included

Five bridge lengths, each a multiple of the Hexfinity standard (42mm flat-to-flat):

• 1x Bridge – 42mm (1HU / 7mm rise)
• 2x Bridge – 84mm (1HU / 7mm rise)
• 3x Bridge – 126mm (1HU / 7mm rise)
• 4x Bridge – 168mm (2HU / 14mm rise)
• 5x Bridge – 210mm (2HU / 14mm rise)

All bridges integrate directly into Atomic Hexfinity layouts and are fully compatible with Roll Hexfinity using the Atomic <> Roll Hexfinity adapters in the Atomic Hexfinity Build Kit.

Bridges from 1-hex to 5-hex length (42mm to 210mm)

Highlights

• Build bigger! Build much bigger structures with far fewer pieces
• Span large gaps: span up to 5 hexes (210mm) in one piece
• 100% Compatible: both Atomic AND Roll Hexfinity

Print Notes

Custom Supports

All bridges use custom support structures built into the model itself for optimal print performance and appearance.

To remove supports:

• Start from the raised end with three small pillars
• Use your thumb to gently squeeze the two outermost pillars inward—they’ll snap off
• Once the far pillars are removed, the remaining supports will wiggle free easily

1x, 2x and 3x Bridges

• Generally reliable with or without brims, but brims are still recommended

4x and 5x Bridges need Special Attention

• The longer bridges are much more sensitive to PLA shrinkage
• Brims are highly recommended to reduce corner lift and layer separation (brims are currently enabled by default)
• If your printer has an enclosure, set the internal temp ideal for your material to improve reliability
• Failures may occur at any point, not just on the first few layers, so keep an eye on it
