Drain Plug Cap - Igloo Cooler

Snap on drain plug cap for Igloo Coolers. ID measures 17.5mm, you may need to adjust scale to fit different coolers. I had several caps missing and had to go up and down 1% in the slicer to fit each one, none were the same exact size. Used PETG, but TPU should also work if you scale down a % or two.
