You should print 2x "Side" parts and one "Insert" part for each spool, then drill a hole in "side" part centers (it is marked), put screw into "insert" part (it's hole is 2.9, so do this before glueing), unscrew it (this makes thread), and glue them together (screws will help gluing). Please note that there are 16mm (for 15mm wide material) and 31mm (for 30mm wide material). You can do your own size - STEP files available. To help winding with a electric screwdriver or drill, print one "Winding Helper" and put M3 screw into it to clamp it into drill. To wind material, anchor end of ribbon through "insert" hole and make few turns by hand to make sure the ribbon is anchored well. Then you can continue doing it manually or use a winding helper.
