Needed a way to store additional filament spools. I didn't like stacking them on top of each other as it becomes hard to manage so I put together this spool stand that holds them vertical and easy to remove.
Cut dowel length to suit your needs obviously. (I've done 8 without any sagging but you can print another stand halfway to support the rod if needed
2 versions to suit 12mm and 16mm wooden dowel rods. Will still work fine on smaller dowels
