    Cuz it so cute! no, was the first batch I ran across plus it was the one that TommyDee used in metal drive housing, plus didn't want different sizes scattered around. Cant find the ones I got but here are some similar.

    Yes I can, why would you want a M5 quick fitting, would it have an advantage?

    I only use M5 threads on the fittings because it provides the stop for the Teflon tubing from the nozzle.
    But even so, I find fittings with too small of a hole for the filament.

    Also, M5 is a better fit directly in the driver mechanism.

    Here is a version of the nozzle I've been printing with for a couple of months...

    Yessir, I second that and second the use of his nozzle. Wow that sounded bad. At any point. His design has worked flawlessly since I printed it and looking forward to trying yours zugok.

    I was not aware of another variant, thanks Tommy good work!

    I can see the advantage of having the "transition" from a "Stock" 4.2mm PTFE tube to the 3DS thin nozzle tube at the top of the housing, as it is farther away from the heat source so less chance of jamming due to expansion.

    As TD said using the M5 to join the different tubes is great. I will start work on Mk II, after my Hockey game tonight.


    Cheers

    Nothing published on the housing. Todd and I are giving it a run for its money.

    Almost done updates, thanks for the great feedback.

    Now uses the same M6 fitting that I used on the Extruder housing. I only 3D Print the nozzle tip thread, for the fitting end I use a M6 Tap.

    When I get some M5 fittings in from Amazon, I will make a M5 variant too. I hope to have the HubCap and Nozzle fully tested and running this coming weekend using ABS for the Hub and PC+ for the Nozzle.

    Regards

    Maybe you can carve some thread bits off the linked nozzle...


    Tube length is 42mm if you decide to print the M5 version. Just keep the blob reliefs oriented.
    The M6 version was for the 4mm tube-through fittings which can be merged with the 2.8mm tubing.

    Sorry for the delay..

    After tons of iteration and tiny adjustments I have nozzle files. One version is best suited for PLA since it prints more easily. The other for Polymaker PC-Plus. Early in my fit-tests I also tested in ABS but found it to be too soft at the time. Probably the PC+ version would print fine in ABS too. I have some PETG that I may try as well.

    I drilled out the end of the M6 fitting so the 3DS tube will fit into it.

    The Polycarbonate one is very durable (as expected) but tends to fit very tightly too (no flex!) . I will have to do a couple more fit tests.

    I used Simplify3D to generate the Gcode, and some support should be used, at least for the PC version.

    I hope to have print tests with the parts fitted in the cube done in a few hours.

    The photos show a few of my "test shots". Blue is PLA, Orange/Black is ABS, white is PC+

    Cheers and happy holiday.

    Thanks TD, that is a good suggestion.

    The link says "File not found"...?

    Cheers
