My wife has a lot of spools of thread. A LOT. And they tumble around in her drawers. So I designed this very simple organizer to stand the spools up at a tight spacing so she can fit a lot of spools in a single drawer and still have them organized and accessible.

The "Small Spool Organizer" is for 100-250 yard spools, and the "Large Spool Organizer" is for 500-1000+ yard spools.

The design is parameterized, but since I've designed it in Fusion360, I can't make it parameterizable on Thingiverse (If there's a way to do this, please let me know!). So I've posted a few configurations (e.g. 3x5 = 3 wide, 5 long spools), but if there's a configuration you want, post a comment, and I can generate a new .stl pretty quickly.
