WK Jeep Automatic Shift Knob adapter

So I have a WK model Jeep Grand Cherokee that I needed a new shift knob for. I printed out the flight joystick, but wasn't sure how to mount it securely, so I tried to copy the bottom of the shift knob that goes into the oe chrome escutcheon.

This is my first ever 3d model, so I hope it helps for people that have jeeps. Please comment or remix, helping is caring. This object was made in Tinkercad. Edit it online https://www.tinkercad.com/things/hicnKz61lbI
