New CTC printer came broken

[EagleSeven]

Oh wow that is inexpensive. These Bizer III's are supposed to be basically the same printer, just with a metal frame instead of wood, and the touch screen of course. The tubes mine have are larger inside, and have that PTFE tube insert. If I get that one you linked, would that eliminate the need for that insert? If so, what was the point of using the one with the insert in the first place? Is it for lower friction?

Yes, idea of Teflon insert was to reduce binding of filament in tube
and to improve seal between tube and nozzle
but I've read that it causes more trouble than it helps.
I know it is really Not needed since we have Never had the type with insert
and ours works Great !

With the All-thread design there's no problem at seal between tube and nozzle
since tube can be screwed in to compensate for short-thread nozzles.

Note: make sure it is made of Stainless-steel
the brass ones are too easily damaged
