I had previously printed a version of this part, but unfortunately, it was my own mistake that caused the print to break and now my pneumatic fitting consistently loses grip on the tube, resulting in ruined prints after several hours. To address this issue, I made some modifications to allow for use with the E3D Threaded Bowden Coupling. The E3D Threaded Bowden Coupling can be found at https://e3d-online.com/catalog/product/view/id/8625/. When using this version, I've discovered that trimming the filament at an angle is necessary so that the point aligns with the side of the gear. If not, it becomes difficult for the filament to feed into the tube easily. I would like to extend my gratitude to joshvv for creating the original design, which can be found on Thingiverse at https://www.thingiverse.com/thing:2144277.
