Bowden tube fixing
thingiverse
It's not uncommon for the bowden tube to come loose from its pneumatic fitting due to the high pressure exerted by the filament drive and the constant movement of the tube within the fitting. To prevent this issue, I've created a small component that securely fastens the bowden tube to the filament drive. This design is inspired by https://www.thingiverse.com/thing:2859900. A helpful trick for achieving a tighter grip on the bowden tube is to twist one wire of a flexible electrical wire around it, making sure to apply gentle yet consistent pressure.
