After using the Bambu Spool Holder with my current setup I noticed I was hitting it when removing a roll of filament. I used the excellent model from MOOO as reference and made this 3 part add on.

All you need is 2x M3x6 screws/bolts that self tap into the small pieces. No supports were used but they would help. I just reamed out the inside with a pointed file and it worked great.

Not a must have add on, but it does help somewhat when removing spools.
