Modified all versions of BastR Bambu Lab Side Spool holder incorporating the Filament Guide from ktothestank Bambu X1 & P1P - Side Filament Holder.
I used the long bed screws that were removed from the bed when unpacking the X1 Carbon to attach the filament guide to the version 2 side spool holder.
