Say goodbye to cardboard spool problems! Say goodbye to respooling messes, say goodbye to electrical tape, caps, and 500 different spools you need to store and sort through when you buy a new brand of filament that comes on a cardboard roll.

This spool is designed to be the exact same size as the Bambu spools so it fits perfectly in the AMS and allows the unit to close properly helping to keep your filament dry. It prints in 3 pieces. 2 sides are exactly the same (so print 2 of them) and have a threaded end and a swappable center adapter to perfectly fit the inside of any cardboard spool that corresponds to it's size. I am making and adding adjusted center adapter sizes as I come across different cardboard spools.

How does it work?

• Gently rip off the side of any cardboard spool. This takes next to no effort on the cardboard spools. Clean up the loose cardboard with your hands so you have your center hole exposed. (below photo shows the universal center adapter test fit into the center. You can place it in first and then screw the side on, but I find it easier to screw the side on first. This was just to demonstrate the fit)
  
  
   
• Measure the size of the center hole so you can pick the right center adapter to use
• Screw one side of the center adapter onto the universal spool side and insert the center adapter into the cardboard. This is a friction fit. You'll be able to turn the spool on the adapter by hand but it will require some pressure
• Carefully flip the spool around and rip the other side of the cardboard off. Then screw on the other side of the universal spool side.
• Done! To remove the filament, simply unscrew the sides and remove it.
• Optional - Place a standard Avery 1" x 2 5/8" label (6460 code) to identify your filament type in the dedicated area on the spool. See model photos

Current universal adapters:

• 82mm - Fits Bambu, Elegoo and Esun spools (others untested)
• 88.7mm Fits Overture and PolyTerra  spools (others untested)
• 76.25mm Fits Eryone spools (others untested)

Test Size Universal Adapters:

To save you time and money, I created miniture 7.5mm tall universal test adapters so that you can quickly print the various size adapters and insure that the fit on your spool works. These are the same size as the universal adapters except much shorter.

If you measure your other spool centers for other brands and send me a message, I can add more universal adapters for use, but you must be willing to test fit, send me photos and provide feedback so others can also benefit.

******All my print profiles are weighted so that the spool stays within 240-250g in weight when complete so that there are no problems with the AMS from your spool being too light.*******
