    I already know your assumptions. I'm suggesting you are wrong.
    Assumptions?? Wrong about what?

    Has anyone tried printing PETG in conjunction with the temperature modifier?

    The heat that gets to the nozzle housing is not too bad. We can reprint a housing to do what we want.
    Getting a good solid part, now that is the challenge which will require more than Cubify for the Cube 3.

    ABS requires more heat than PETG. Are you saying the fan cools the metal where the plastic contacts it enough to not melt it when printing ABS? Or are you referring to only printing in PLA? I don't have a way to check the temp myself.

    The push-nut is very well isolated from the heat source.
    This is the part that is most at risk due to the spring (which is still needed).
    The fact that the push-nut has so little common contact with the metal tube makes it a very poor thermal conductor... which is good for us.
    Clearance to the stainless steel tube should be maintained.
    What adds heat to the tube is the heat of the filament being withdrawn on the pull-back.
    Even that is well insulated with Teflon tubing.

    There is a fan venting the region. I have no idea of the temperature gradients within the housing or along the metal tube.

    Damn! I just lost the .cube3 file to "load" filament from our Free HUBs? Anyone seen it?
