This project is my approach at making Filament Spools useful again. Therefore I designed 4 different types of drawers that can fit inside the spool and can be easily opened. Those drawers are held in place by 2 M3 screws that work like a hinge. In order to assemble and stack those drawers you most likely will need to drill some 3mm holes for the screws and also split some spools in half. My design is based on the Spools from Polish filament producer Plast-Spaw so if you are not sure if those drawers will be compatible with your spools you can download my .STEP or .F3D file and measure all the parts for yourself (Or remix them as as you wish).
