I had a pass-through fitting lying around and wished to use it on the printer to make a neat looking continuous reverse-bowden guide, and ended up with this model. Bear in mind that this is my first time using Fusion, or even CAD in general, so open the .f3d project file at your own risk. :)

In the example image, I used Polyeterra PLA+ Orange with 0% infill and a generic M10 plastic pass-through fitting with 0.75 thread.
