Black steel pipe fitting

This custom-designed part was created in Fusion 360 to mount a wooden shelf onto a 1/2-inch black cast iron pipe. The pipe slides into a cylindrical opening that closely matches its outer diameter, allowing for a snug and stable fit without requiring additional clamping. The part is attached to the underside of the wooden shelf using screws through pre-drilled holes. This design provides a secure and minimalist solution for integrating pipe-based supports into shelving or furniture applications.
