This is a replacement piece of hardware for a window. I didn't find a make/model/SKU anywhere I looked and didn't see this exact piece at the home centers so I decided to make a duplicate myself. Besides removing some small supports from under the screw holes and the hook the part was installed directly off the printer. It feels as strong as one of the original injection molded parts with 15% infill.

Its one of the first parts that I've made with my printer and the very first one that I've drawn up from original dimensions myself.
