Whether you're;

-Someone who needs to convert your larger (3-5kg) spools to much more manageable-sized ones.

-Someone who buys spool refills to do your part to save the environment.

-(Or in my particular use case, you're) Someone who utilizes a Bambu lab printer with an AMS and needs to move your filament from a cardboard spool to one with more grip on the edges.

This is the reusable spool for you.

This spool prints in two threaded pieces for ease of printing and I would highly recommend supergluing them together as you'll likely never need to take the 2 halves apart and would not want the filament on this to come unspooled.  

This model comes with a few great features baked-in that I've noticed in other spools, but also a set of ID tags (inspired by the HSW organizational system) so that you can quickly know what you're grabbing for each time you pick up a spool of filament. I even left a blank one so that you can edit it to add whatever fits your needs. Whether you want to have a plaque that displays the manufacturer name, a logo, or even a QR code that takes you to a Google Doc that you've set up to remind you how to best run the filament (yes, this one is very specific, but), the possibilities are endless.
