    DYI - Cartridge Clamp Repair Part

    3dsc3cartcatch_cube3.zip

    3dsc3cartcatch.zip

    Got some cartridges that don't lock in anymore?

    Got the fix for you.

    Bust off the other side and print this:

    Takes exactly 1:11 so I included the .cube3 file to prove it.
    PLA on the left. The print is set back so the face is on center.
    And it has its own supports.

    Also attached is the STL if you want to play with it.

    Thanks, I believe that's what I need. Where's the STL?

    Edit:
    Nevermind... They were so close together, it looked like one link.

    Wait, that's made for when you have the outer cover on right?

    Yes to the outer cover but not required!
    It also holds the cartridge at the flanges. Scratch that...
    It is a solution. I'm printing one with a wingless cartridge now.

    You will need to put a pad between the driver and the clamp to make up for the difference.

    Don't you like the covers?

    No, they're a pain in the @$$ to take off, and it seems I have to do so too often.

    Would it be hard for you to add the difference to another STL for people like me?

    What would be nice is to completely replace the cartridge with a "hub" that just has the extruder and chip. Or maybe even have the chip attached separately. You could also add the threaded hole for the quik connect and a guide for feeding the filament into the extruder. Of course, this is for people who feed the filament from an external spool.

    ...okay, Don, for you and you alone

    I offset the front with a 3mm deep bump.
    That should sit on the metal driver.

    I didn't want to change the gripper length.
    That is fitting nicely.

    one can double sticky foam tape these to a cartridge,
    or leave them loose and use them only to clam the cartridge.
    Makes removal a whole lot easier.

    Just for meeeee? Why thank you! You shouldn't have. Wait, I take that back. You should have.

    So, on this one, does DIY mean "Don It's Yours"?

    I'm printing it now and going to bed. I'll let you know tomorrow how it turns out.

    I don't put that much stock in the quality of the print when it comes to longevity.
    For that reason I will also not put time into a fools endeavor.
    Right tool for the job and all that.

    Like I said before, you can merge different STL's on the build plate, and it will build them together.
    What you're asking for is already on Thingiverse, right?

    Great! Many thanks, yesterday I have just broken two cartridges, they are made to use and throw the garbage, the manufacturer did not think to give as much use as we are giving us with the hack ...

    It is a good idea to design a mod to remove the original cartridge and that only contains the chip and retraction mechanism, although my knowledge of design does not reach so much complexity ..

    Thank you!

    I could easily model the rest of the drive head, but it really is not the right thing to do.
    There are so many functional elements in the shell that contribute to its stability that anything you remove is a compromise.

    The only thing I find worth while is the adjustable drive by adding the spring.
    That could solve flexible filament.

    I made the clamp because we can now hot-swap filament without removing the head.
    I broke two cartridges trying to remove them while the printer was still running.
    Normally, when the printer is resting, I've never had a problem removing these things.

    With the clamp, I can remove the clamp and the cartridge can be pulled separately.
