My son came to me and asked if I could print one of these for his car. His vent connector had broken and he took one of the working ones and brought it to me and I took measurements and I came up with this simple design. I made the ball connectors a little bigger on his model so he could sand them down so he had a snugger fit. This connector piece should be made out of PETG because it will be used in a vehicle and get very hot.
The author marked this model as their own original creation.
