I needed a hook for a rack that my husband built to display my bells for an art show. I wanted something easily positioned, simple to use, and that would stay with the rack rather than removed with the product being displayed. The rod for hanging the hooks is roughly 1.5inches in diameter (hand turned, so not perfect). The hooks were sized to fit loosely over that.

I printed in PETG with three perimeters for strength. Possibly overkill, but I wanted something durable.

Easy print.
