I was looking for a clothespin basket but didn't really find what I was looking for. So I opened up Vectorworks and quickly drew this up. It prints in two parts and just needs some glue to assemble.

I printed this out of regular PLA with marble look and it is holding up perfectly so far. Print the hook lying flat. I didn't put any clearance so you might have to scale it down a bit to fit perfectly. I printed mine at 98% and had a nice press fit. After printing is done, just put some superglue in the center hole, insert the hook and you are ready to go.
