I created this hook for a 2024 Jeep Wrangler with the McKinley upgraded leather seat package. It may fit other models. Its best to print this with ASA or ABS because of the temperatures it can be exposed to in a parked vehicle. Simply remove the headrest slide the bracket on the post and reinstall head rest. I printed this using Cura 5.6.0 on a Elegoo Neptune 4Pro.
The author marked this model as their own original creation.
