Ultimate Reusable Spool - BambuLab Refill Swapping

This spool is fully 3D printed and solves one of my biggest frustrations:wanting to use a filament color for just one or two prints, then switching colors—only to realize I’m out of empty spools.Even with 15+ reusable Bambu Lab spools, this still happens to me more often than I’d like… and it’s incredibly frustrating.That’s why I decided to share this model—I’m sure I’m not the only one running into this problem. Here is a video of me showing how to use it - The spool is identical in size to an original Bambu Lab spool and is designed specifically for Bambu refills.I recommend printing it in PETG or Tough PLA, but feel free to experiment. I haven’t tested standard or matte PLA yet, though it should work just fine.If you’d like this design adapted for other filament brands, leave a comment and I’ll look into it.If you enjoy this model and find it useful, consider buying me a coffee or a beer ☕🍺—it helps support future designs!
