Qidi X-Plus3 Back Wire Ingress Plug

I've been going through and systematically closing all of the open holes on my X-Plus3 because ASA and ABS smell bad (and styrene gases are toxic) and I want all of the air leaving the printer going out the exhaust hose out the window and not leaking into the room where I might breathe it.

This is just a basic press-fit plug for the hole where the wire going to the toolhead enters the chamber.  This is the larger, lower plug in the picture.  The filament tube plug is (not my work) this model, which fits pretty well.

Since the chamber temp is capped at 65C, pretty much any filament should be fine.  I recommend PETG/ASA/ABS.
