Made a cover with clips to cover the hole in my console where the aux jack used to be. I run my aux jack underneath to a Bluetooth receiver. Based off of the original jack from my 2012 Mazda 5, but looking at images on google it looks like it'll work for any modern Mazda with the vertical rectangular slot.

Could easily be modified to hold a female 3.5mm jack or USB port if yours is broken.

Print with the clips pointing up towards the cover face. I used Cura tree supports.

UPDATE

I've added two designs, one with a hole and a recess for a DPDT toggle switch, and one for a 12v PWM controller/potentiometer. They are also shorter, no longer requiring supports for the clips, when printed pointing up.
