    HubCap V1

    Parts published here:

    https://www.thingiverse.com/thing:2735871


    I am getting close to finishing this printed alternate extruder hub...the HubCap V1.

    After getting so many print failures in fine 70nm mode, I started looking into replacing the filament feed system, based upon what TommyDee and MegaloDon have already done with the FilamentHub and FTF Hub.

    There is aspects of the both I like, such as Dons very complete cover and chip holder, but I also like the simplicity of Don's FH with the Bowden coupler directly threaded to the metal hobb-gear housing. I also found that my hub gets very warm so looking to find a way to channel the airflow from the stepper fan to the metal housing.

    I also added neodymium magnets from HomeDepot to help secure the hub into place, as the clip is not very strong.

    Here is a few pics, parts printed on my Taz 5. I will print them out on my Cube once all it actually working. Once it is all done and functional. I will post the STL's with the settings that worked for me.

    Huge thanks to the other members of this forum for being so helpful.

    Thanks.

    The combination on fit+clip+magnets = secures the hub into place.

    Printed in shitty S3D PLA, will print in ABS when design is final.

    Just happened to take apart my old bulk filament with the switch and it is eager to try the hubcap!

    Thank you. I hope to have the final hubcap ready in a few days.

    I think I am going to make the hub a "complete kit" with a new nozzle file too.

    Based upon measurements of the 3DS parts and re-imagining the (awesome) print head that Don made. The main PTFE tube goes all the way to the metal end, meeting with the thin PTFE.

    IMHO making a screw-on end cap makes the part easier to print and maybe stronger too? Tests will tell. I hope to have all the parts ready very soon.

    The PTFe goes to the nozzle end where the thin tube is.

    NIce! Like the screw cap at the hotend. Could you do a file with the M5 quick fitting?

    Thanks ztoddman

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

    Cheers

    (make the hole around the metal tube somewhat larger. You only need a lip there...)
