Filament tube expansion port

This restores the official filament tube expansion port, suitable for X1/P1 /P2S/H2C/H2D/H2S (hanging ears are not designed; I don't have the dimensions), and can also be used with A series multiple external filament spools, costing only about 5 yuan

Installation requires five or fewer accessories, both Figure 1 and Figure 2 are acceptable, buy whichever is cheaper (you probably have a lot left over from making my previous models, or you can disassemble five A series external filament spool feeders, or disassemble five X1/P1 series pneumatic quick connectors)

After printing is complete, start processing the hardware parts

Remove the bottom plastic parts of the four pneumatic connectors (the bottom is easy to disassemble)

The internal clips can be easily removed using needle-nose pliers or tweezers

The four clips need to be inserted into the four circles in the image, ensure they are secure, it can still be used even if not tight

Place the four circles into the holes of the cover plate

Cover with the cover plate

Install the rear pneumatic connector, just press it firmly into place, when inserting the rear PTFE tube, make sure it is fully inserted (the tube should be inserted about 1-1.5 centimeters), if not fully inserted, it will affect smoothness, if insertion is difficult, chamfer the end of the PTFE tube
