X1 AMS/External Spool Splitter

Yet another splitter that enables you to use an external spool in addition to the AMS on your X1/P1 printer. It replaces the in-line tube connector on the back of the printer. Unlike other splitter models, this does not require those fancy tube fittings - just two M3 x 10mm screws to clamp the PTFE tubes in place. Note that the side port goes directly to the spool on the back of the printer, so no additional PTFE tube is needed. This prints horizontally so that the print lines flow in the same direction as the filament path for smooth operation. However, the roof of the straight-thru channel might be a little rough, so I recommend scraping that smooth with a small diameter rod, drill bit, or needle file. Honestly, I'm not sure why Bambu didn't include this sort of thing in the first place.
