Spinfinity - A rotational system for Gridfinity, Multigrid, and Multiboard

Spinfinity brings the power of twirling to your Gridfinity and Multigrid setups. The Spinfinity system includes adapters to mount spinning Gridfinity or Multigrid baseplates on Gridfinity, Multigrid, or Standalone surfaces! Get ready to spin your bins.

The design

• Rotates smoothly, even under heavy load
• Uses standard base plates and connectors
• Compatible with Gridfinity, Multigrid, and Multiboard plates/tiles
• Mounts securely on Gridfinity using standard 6x2 magnets, Multigrid using mid-thread bolts, or any flat surface using optional suction cups
• Supports mixing and matching systems (spin your Gridfinity bins on a Multigrid plate and vice versa - I literally cannot stop you)

Mounting options and required fasteners

• Standalone
  • Optional 0.8 inch suction cups (4)
  • Appropriate screws or bolts depending on your surface
• On a Gridfinity baseplate
  • 6x2 magnets (4)
• On Multigrid baseplate
  • Screw-In Fasteners (Bin to Plate) (2-4)

For all setups

• 3-10 8mm steel balls. More is better.
• Spinfinity Bearing Cage. You can optionally skip this if you use 12 8mm balls.

For a Gridfinity setup

• Your preferred base
• Your preferred Gridfinity baseplate (as long as it has the screw/magnet holes)
• Spinfinity Bushing (Gridfinity)
• Spinfinity Gridfinity Weighted Baseplate Adapter
• 4 M3 screws

For a Multigrid setup

• Your preferred base
• Your preferred Multigrid Base Plate
• Spinfinity Bushing (Multiboard)
• Spinfinity Multigrid Base Plate Adapter
• Multiboard bolts or clips to attach the bushing to the baseplate. The appropriate hardware will vary depending what you’re putting on your baseplate. The Base Plate Adapter works like a Tile, so you can use Bin Through Plate to Tile bolts and locks if you’re mounting through a bin or Bin to Tile bolts and locks (thin head) if you’re mounting under a bin.

For a Multiboard setup

• Your preferred base
• Your preferred Multiboard Tile
• Spinfinity Bushing (Multiboard)
• Spinfinity Multiboard Horizontal Tile Adapter
• Multiboard Brackets if you want to mount additional tiles perpendicular to your base tile

Notes

• There is necessarily play in the spinning mechanism. You’ll mostly notice this if whatever you’re spinning is not balanced.
• The Gridfinity adapter mounts using M3 screws. The screw holes are tight, but should self-tap.

Ideas for the future

• Additional adapters for central attachment on odd-numbered Multiboards and even-numbered Multigrids (the Gridfinity adapter already supports any combination of even and odd numbered sides)
• Support for alternate bearing ball sizes
• Tight bushing option for less wobble with unbalanced loads
• Option to rest at set positions (e.g., 0, 180)
• Multiboard base (with appropriate bearings for vertical spinning)
