Simple under desk/shelf spool holder

Like many, I often find myself with more filament than I need and running out of storage space. To solve this, I’ve created an under-desk spool holder, which can also be mounted under a shelf or even vertically. I’ve tested this holder with the following spool brands and can confirm they fit when using the mounting guide: Bambu, Esun, Eryon, Sovol, and CC3D. The mounting guide is designed to accommodate any 200mm spool. You can use the open-ended rails to store multiple spools in a row. For convenience, I recommend storing the same type of filament in a single run, as you’ll need to remove all the spools to access the last one in the row. The mounting guide provides a loose friction fit, making it easy to remove once the rails are mounted.
