Snoopy Gear Shift Knob for Highlander

This is a remix of Anthonylu's Snoopy model (https://www.thingiverse.com/thing:1261540) which I made into a gear shift knob for a highlander. The model screws (no threads but perfect fit) on the gear shift screw, locking it from being pulled up. It will rotate but should not come off without unscrewing it. Let me know how it goes, I am a new to 3D printing and modeling so any feedback would be helpful!
