Davinci Pro 1.0 Bowden tube to hotend fix

thingiverse

As I was dissatisfied with Davinci's approach to integrating the entrance of the Bowden tube into the top of the hotend, I took it upon myself to redesign this critical area to ensure a smooth and uninterrupted flow of the filament through the Bowden tube. The concept revolves around relocating the double pneumatic coupler from its current lateral position within the hotend to a fully vertical orientation. This strategic move allows for a seamless 90-degree curve, where the modified component slips effortlessly over the Bowden tube. A visual representation of this innovative design can be seen in the attached photograph. The original layout, which positions the double coupler at an angle, inadvertently pinches the filament as it navigates through the hotend's interior. By making this simple adjustment, print quality has seen a significant improvement.
