Modification of the STEP spool parts to remove the filaments with the inner core only, for easier drying and storage.
The spools have cutouts for velcro to hold the coil before opening the spool. So the reverse process of inserting the Bambulab refill packs without the coil.
In addition, there is a core coil for winding, which is not made of cardboard and therefore cannot absorb moisture.
What also works very well is inserting the RFID tapes of the refill spools, apparently the AMS even generates the approximate consumption over the revolutions of the spool. At least that's how it works for me. 

Added an filament insert-line to show the winding direction and get a good 1. winded layer.
