GRITS  Gridfinity Rotating Integrated Tower System

This is the Gridfinity storage system you didn't know you needed:

A fully modular, 360° rotating tower with precision ball bearings at the base. No more reaching to the back of a box. Just spin, grab, done.

I know the extra hardware makes it harder to replicate, but trust me, it's worth it. The rotation is incredibly smooth and precise. But if there's enough demand and it gets at least 1,000 downloads, I'll make a 3D-print-only version. 

What makes this different

Every other Gridfinity tower sits static on your bench. This one rotates. Two high-quality ball bearings are integrated directly into the foot, giving you a buttery-smooth, wobble-free spin that feels premium — not like a fidget toy, like a real tool. You can also install magnets in the base so it “snaps into place” at four points.

The tower is built around standard Gridfinity bins, so you're not locked into a proprietary ecosystem. Use whatever bins you already have, or print new ones. Every slot is labeled, every drawer has a purpose.

Bins you can use:

1x1x3 or 6 (actually 7)

1x2x3 or 6 (actually 7)

Specs

• Gridfinity compatibility Full standard (42 × 42 mm grid
• 8 single Bins per Level
• 2 height options:
  • 35mm for 1x1x3
  • 70mm for 1x1x6(7)
• Unlimited freedom to stack the Tower :) Make it the size you need
• 360° continuous Rotation
• 2 Ball Bearings 608 and 6004 from the Makersupply

Modular by design

The tower is built in stackable height units:

• 35 mm modules — ideal for screws, nuts, small electronics, SMD components
• 70 mm modules — perfect for larger fasteners, bearings, tools

Mix and match freely. Build the exact height that fits your workspace. The modular system means you can print only what you need and expand later — one level at a time.

Designed for makers who mean it

This isn't a concept render. Every part shown was printed, assembled, and used daily in a real electronics workshop. The drawer tabs are angled for single-finger pull. The bearing seat is toleranced for a solid press fit — no glue needed if printed correctly. You can customize the label yourself in the slicer.

Print notes:

• Designed for no support
• The Base is 150mmx150mm so should fit on every Printer
• 0.2mm Layerheight is optimal
