Headphone Hanger

Second attempt to upload this! This hanger hooks on the tubular frame of a cheap metal rolling cart. it's braced to be level in spite of the open framework of the cart. I use them to hold my head mounted magnifiers but headphones fit easily as well. No supports needed but use fill of 50% or more.
Each model has a progressively longer 'heel' that one can grind down for a perfect fit.
