This model for the retention hook for the visor in a Pontiac G6 has been iterated upon to optimize for strength and low material usage.
It is recommended to use a carbon fiber filled filament such as ABS, ASA, or PA due to the high temperatures in a vehicle as well as strength for the clip.
The flat face at the front on the bottom is a good orientation to print for strength of the hook and reduce supports for alignment pegs on rear.
The author marked this model as their own original creation.
