Hook for wire shelving unit

thingiverse

The metal rack, a wire shelving unit commonly found in Japan, features a versatile hook attachment that securely fastens to the pipe post. Two sizes of pipe diameters were created: 19 mm and 25 mm. The hook and clamp design are widely used. By modifying the hook component, it's possible to apply this metal rack system to various uses. In one example, the hook was designed specifically for electric screwdrivers.
