This is a tutorial on how to transfer a filament spool from a cardboard spool to a Bambu Labs Reusable Spool.  Step 1:Get spool Step 2:On Bambu spools it has a index notch for their filament I clip it off with a pair of snips (you can also use that index notch if you cut a notch in in the cardboard core of your filament.).Step 3:Peal off one side of your cardboard spool and the inner circle coreStep 4:Put the parted half of the spool holder on (should slip right on).Step 5:Flip it over and move over the filament end to the new spool side for safe storage while you peal off the other half of the cardboard spool.Step 6:Sometimes depending on the filament brand the inner cardboard cord can be loose on the center so just shim it with something like a piece of filament/cardboard so it doesn't slide around the middle of the spool.Step 7:Grab the other end of the reusable spool and lock it closes and now you should have a plastic spool ready to go!
