Simple 12mm rod rack connectors

Build rack bays in any size, shape, or configuration with this versatile system of 3D-printed rod connectors, designed specifically for 12 mm outer diameter rods.

These precision-fit connectors transform standard rods into a fully modular structural frame — ideal for DIY fabrication projects.

 

Designed for 12 mm OD rods

 

Fully modular geometry
Create frames in any dimension — width, depth, or height — simply by cutting rods to length.

 

Multiple connector types available

• Infinite layout flexibility
  Build rectangular rack bays, cubes, towers, wall-mounted frames, angled structures, or irregular shapes.
• Lightweight yet strong
  Optimized internal geometry provides high rigidity while minimizing material use.
• Fast assembly
  Slide-fit or fastener-secured designs allow quick construction and easy reconfiguration.

⚙ Assembly Method

1. Cut rods to required lengths
2. Press rods into connector sockets
3. Apply glue (optional) for permanent joints
4. Expand or reconfigure anytime by replacing rods

No special tools required.
