About this 3D model

This simple ring is designed to fit in the holes on typical sheet metal wire rack shelving. The spacing between the holes on my shelf is 37mm (1.5 in). The large hole is 14mm wide and the slot is 7.5mm wide. This one is great for storing tweezers, pliers, or other hinged handle tools. I'm fairly sure this is the model of shelf I based this design on: https://www.lowes.com/pd/edsal-72-in-H-x-36-in-W-x-18-in-D-5-Tier-Steel-Freestanding-Shelving-Unit/1000525
