A lady I know wanted shorter curtain hangers as the ones provided in her kit stuck out almost double the length of these. I kept the design similar to the metal ones she had but since its printed and plastic I made them a little thicker and wider. I hung a 20 pound weight from one and although it wasn't pretty it didn't break so I'm confident a pair of these will hold some curtains just fine.

My printer was able to print without a brim or supports even the elongated hole but you may have to enable them.
