Upcycled Spool Shelf

Repurpose those empty spools by turning them into mini shelves!  This was designed for Kingroon spools, but good chance it will work with others as well.  I printed this with PETG for the part that's connected to the wall/elbow, to avoid any sagging in future (might not be an issue), and PLA for the extensions.  I added negatives for 5 screw holes, and left them in place for you to adjust to your liking if needed.  The spools make a nice height for miniatures and fidgets.

Print one wall mount, and an extension for each additional spool you want to add.  Note: the tolerances when printing one piece in PETG and the others in PLA were tight when intermixing the materials.  When using same materials, it's much looser.  Obviously YMMV depending on filament brand you use.
