A spool holder using inexpensive pegboard hooks and a section of PVC pipe.

Print instructions

Print in PETG at .2mm layer height. I suggest supports (although they are a pain to get out of the hole that holds the end of the hook). I used a high infill (50%), although a draft with 15% felt sturdy enough.

You will need hooks that attach to the pegboard; I designed this to work with the Crawford #18580. You can find a pack of 2 at Amazon at https://www.amazon.com/dp/B000MKK4ZE. You'll also need a section of 1 inch PVC pipe; I bought a section I found at the hardware store, cut it to size with a hacksaw, and sanded the ends.
