I have two UOs, in each the bowden tube pops out of the hot end isolator coupler, disrupting the print and causing clogs. The tube is all scratched. I tried snipping the tube of one, it still pops out ... the coupler must be damaged, right? For some reason, Ultimaker's online payment service is unale to accept my payment via credit card. Does anyone know of an alternate source for these parts, preferably in the USA? Please advice. Thanks!

    I had that problem on my UM2 half a year ago.

    Solved it by printing a thicker clip to put force on the coupler, making it grab the bowden tube better.

    It has worked perfectly since then.

    I just uploaded the stl-file to youmagine in case you want to try this: https://www.youmagine.com/designs/ultimaker-bowden-clip-thicker-version

    You should be able to scale it in the Z-direction if you need it to be thicker or thinner.
