    I found the original bigbox filament feed tube was always moving, caused by retraction. The built in clips in the cable brackets just never held it so after a while it'd creep up and overhang the build plate too much.

    I redesigned the first bracket with 1/8 BSP threads to fit the common 4mmOD push-fit pneumatic fitting. I got the fitting for £1 from my local air line shop.

    I Like that. A simple and inexpensive fix.

    Mine (BB 1.0 Dual) were the opposite. Too tight and damaged the teflon tubing pulling it through. Nonetheless, super clever and slick looking :)

    Mine started off too tight, so I reamed them to 4mm, so they became too loose!

    I don't have any issue with mine, but I like the look of it. I'm curious how easy to feed this is ? At present, the bit that pops below the bottom bracket is something I can hold on to and then push the new filament into. This almost looks like i'd be scratching around hoping to hit the opening, as it'll be below eye level and hidden underneath ... or is it much easier than that in practice?

    You can see in picture 2 the inlet on the threaded side which is a fair size with a chamfer to guide the filament in so it's easier than threading it into the tube itself.

    But its a fair point. I've modified the model to taper the holes on the underside to make it even easier.

    Ah. I see, that screws all the way through flush with the other side I take it. If so, not sure a taper would help. If not, a taper would definitely be handy to guide it all the way in. OK, I see from the model it looks like it will guide it all the way. Nice.
