My organizer/drawers are designed to fit Bambu reusable spools. The cardboard with the RFID must be removed to ensure the trays fit the spool's diameter.

There are four different sizes available, and each size has a version that can be divided into smaller compartments. You can mix and match different sizes to best suit your needs.

UPDATE: I’ve made some requested changes:  

1. The small RFID/Refill pin is no longer needed for a perfect fit.  
   1. Only three dividers are included, due to the change for the RFID/Refill pin.  
2. A version is available that can be connected to the spool using a 3mm iron rod
   1. the connector pin has been replaced with a 3mm hole.
