Tinkertoy Hub & Spoke Connectors — Geometric Kite Fittings

Precision-machined round hub-and-spoke connectors — the essential fitting for faceted, geometric, and polyhedral kite designs. Often called “tinkertoy fittings,” these durable hubs accept multiple spars radiating from a central point, making them ideal for star kites, box kites, cellular frames, and any design requiring multi-spar junctions. Available in 6mm and 8mm/10mm tube sizes with 6 or 8 spoke configurations. Need more spokes? Stack two hubs for even more connection points.

Available sizes (tube diameter × spoke count):

  • 6mm × 6 spokes
  • 6mm × 8 spokes
  • 8mm × 6 spokes (currently out of stock)
  • 8mm × 8 spokes
  • 10mm × 8 spokes

Why tinkertoy fittings?

  • Precision machined for consistent fit and long-term durability
  • Round hub design distributes load evenly across all spokes
  • Compatible with carbon and fiberglass tubes in matching diameters
  • Stackable — combine two hubs for designs requiring more than 8 connection points
  • Versatile beyond kites — useful for geometric structures, STEM builds, and maker projects

Common uses: Faceted and geometric kite frames, star kites, box kite junctions, polyhedral kite builds, STEM structural projects, and multi-spar hub connections.
