20mm Spool Holder

Small core spool holder, inspired by a design by Eric Lien. This is a low friction spool holder, I don't actually use it anymore since I prefer spool holders with more friction (some of my spools are self-unwinding), but I figured I'd upload it anyway since it might work for some. It's designed to be small enough to fit the Taulman mini spools and long enough for all the 1kg spools I've seen.
