I've been reusing the Bambu cardboard spools to wrap my various wires around and finally decided to make a mini filament spool to hold it and keep the wires from falling off. I thought this might be useful for some other people too, for wires, rope, yarn, etc. I got inspiration from @Brandido02's remix of the official Bambu Spool found here: [https://makerworld.com/en/models/16747-bambu-reusable-hex-spool#profileId-15531](https://makerworld.com/en/models/16747-bambu-reusable-hex-spool#profileId-15531)

The center ring is the same one from the remix including the tab on the center ring to hold the cardboard spool, it works with the Bambu and remixed spools, and with clip on that file. I have included a .3mf, .stl, and .obj. This was done on my X1C with a .4mm nozzle and printed in PLA. Both halves print on one plate, along with the clip, and prints in ~2.5 hrs, no supports needed. This mini spool is overall ~35% smaller in diameter than a normal spool, the outside rim radius is 35.3mm narrower.
