Adapter between Kreg Pocket Hole Jig K5 and Hilti shop vac 36mm hose

It press-fits onto both the hose and the swivel vacuum port on the Kreg K5 with the connection being pulled together more when the vac is running. It only protrudes 15mm inside the K5 fitting, and the thickness tapers so as much as possible it won't impede the airflow

I printed it in eSun PLA blue which is an okay approximation of the Kreg. 

You'll want to print it vertically, Hilti end down. I've included the project file showing the settings I used including the scarf seams and fuzzy skin modifier which gives it a grip effect.
