About this 3D model
This is a remix of some parts from BC 's Bambu X1C side mount spool holder v2 . I added a thread to “Filament guide PC4-M10 fitting.stl” which fits the PC4-M10 pneumatic connectors. I've also printed BastR 's “NEW V2 Bambu Side Spool Holder X1 and P1P ARC” . So I already had his spool roller printed out and didn't want to reprint it with smaller dimensions. Therefore, I remixed the spool holder to fit the old roller with 112mm (instead of 93mm of the new one).
