Bambu reusable Spool with fully integrated clip

I took the original spool provided by Bambulab an made some changes: I created two versions, one with a diameter of 18cm and one with the original diameter of 20cm. The 18cm version can be printed on the A1mini - I like the 18cm spool more because it allows me to store the spool in two rows one behind the otherThis spool has a surrounding filament clip in the edge so that the filament can be clipped to the point where it is currently locatedI added a hex pattern to save filament as well as inserted some holes in the core to fix the filament when respooling On the third printing plate there is a label for marking the filament on the spool and a test section of the spool. If necessary, you can use this to test in advance in twenty minutes whether the filament clip and the hole in the core have the appropriate diameter. This means you don't have to print an entire plate for 2.5 hours I made a surrounding filament clip for existing Bambu spool:https://makerworld.com/en/models/741564Upd
