Bowden and Wire Support for Ender 3

thingiverse

I encountered a problem where the constant flexing of the Bowden tube in the tube fitting led to its failure (the destruction of the stainless steel teeth). To tackle this issue, I attempted to minimize the flexing load on the Bowden coupler by first isolating the wires using dpetsel's design. Subsequently, I decided to add support for the Bowden tube itself and created a new version that addresses this problem.
