The thin hanger bars are rather badly spot welded to the tube frame, and tend to snap off on this particular el-cheapo drying rack (see last image). This fixes it, but note that it won't hold as much weight, as the bars won't be fixed horizontally, and will bend and come out of their holes. You could maybe remedy this by drilling through the clip (and the bar), and fitting a thin bolt throught the hole. I haven't bothered, as it works ok like this too.

Works for racks with 12 mm frame tubing and 4 mm bars. Printed in PETG.
