Spool Tray Tower

These files let you recycle all those old 3D printer filament spools we have lying around into a handy storage tower. The trays have room for little paper labels and 3 slots for dividers. Great for electronic components, crafting items or workshop bits and bobs. For each 200mm diameter spool you will need: - 8 x Spool trays - 1 x Spool connectors - 1 x Spool Tray Rail - and as many tray dividers as needed You can connect multiple spools on top of each other to create storage towers.
