Filament Spool based Filament Spool Storage

One of the most common questions I hear from people that are new to 3D printing is, “What do I do with all these empty filament spools?” It’s a great question and aside from the obligatory “spool organizer” response, the options are fairly limited. I’ve long thought that the spools themselves could be used as raw materials for building larger projects. If you do enough printing, eventually you’re going to not only have lots of empty spools hanging around but lots of full and partial spools stacking up that need a home. With minimal additional parts you can use those empty spools as a raw material to create a modular, expandable storage space for your full spools.

Included are models to accommodate spools from several major filament brands - Atomic Filament, Prusament, Hatchbox, Esun (transparent spools), and Jessie (from Printed Solid). The dimensional differences between the brands are minor but important in a ‘load bearing’ application of the spools as a raw building material. Yo
