Cheap clothes drying rack wires have a tendency to snap, breaking the weld connecting them to the frame.

This design consists of 2 parts, that wraps around the wire and the frame, joined together by 2xM3 bolts and nuts, that you need to source at your local hw store. Ideally, the bolts will have a length of 7mm, in order to obtain a flush design. As you can see from the pictures, I used longer bolts (12mm) that I had laying around, and they stick out. My intention was to cut them, but I'm lazy inside.

The design is tailored to the very common clothes drying rack found everywhere in Europe (dunno about the US and rest of the world). Essentially, it works best if the wire has a diameter of 2mm and the frame tubing 12mm.

The bottom part can be printed “horizontally”, i.e. laying on the bed, while the upper part should be printed on the side, see slicer's screenshot. In this way, no supports are needed.
