Spacer for bottom of extruder

Fills the void between extruder and hot end
I had a horrible jam of knotted hot filament in that bottom-of-the-extruder space which necessitated a complete teardown, so I made this to fill the gap. Normally I'd have a chunk of PTFE in there but the pieces I have don't fit. So I made this one. Might try printing it in nylon so the filament slides smoothly but ABS works just fine.
