Hat rack mount bracket Chevy Silverado

I made this bracket for installing a hat mount in my truck. This way I didn`t have to drill any holes or destroy the roof in any way.This fits a Chevrolet Silverado 2017 and it`s very easy to install.
The top bracket fits into two already made holes in the overhead compartment, and then I just slid the bottom part underneath it so it sticks into place. I made two holes for attaching the brackets together, but I found out that it`s not necessary.
I printed the top part with only about 55% infill and 2 walls because it`s not the part that gets the most stress.
The bracket itself I printed with 75% infill and 3 walls.
