I made another thing. I've got an aftermarket Double DIN head unit, and the Metra 95-6549 Double DIN dash kit. The kit comes with two useless panels for where the ashtray went, so I used their panel as a template and designed my own so I could put the HDMI & USB-C inputs for the head unit there. It works pretty well, though someday I might try and inset the panel similar to how the cigarette lighter panel is so I can get the connector inset and vertical. But for now, this works. STL attached.
