Optimised Filament Spool Drawer (Uses ~50% less filament!)

thingiverse

I've always liked the filament spool storage tower, but existing designs waste huge amounts of filament - costing more than it would to buy a storage box. ] This design reduces the printed material by ~50%. I have minimised the wall thickness and removed the walls which are replaced by any <0.5mm thick sheet material. In the picture I have used Card but literally any cheap/junk material will work! To attach the drawers to the spool I tend to use wooden BBQ skewers because they're cheap and easily available, model kit sprue arms also work well if you have them lying around.
