If you want the files I can post them. I had to use heat (PLA) to get these parts to mold correctly to the coupling. Re designing the pieces with an ID of 9.25mm would be a way to avoid using PLA.

It is no permanent solution that's for sure.

I am no Bowden expert but I would think that having the ID close to the size filament we are using is important?


From left to right
E3d ID about 2mm
Bulldog about 3mm
Bulldog about 4mm

I used an exacto to whittle down the end of the tube until it fit the E3D coupling.
