Hyundai Ioniq 5 Tweeter Bracket

I'd recommend printing in PETG since it's going to go inside a potentially hot car. It's also a (very) tiny bit wider than the gap between the screw holes so the flex of PETG is nice. I used 3 walls and 40% infill. I printed with the flat side against the bed and tree supports holding up the screw holes. The model is for the driver's side, just mirror across the X axis for passenger's side. I just mounted the tweeter to the flat inside surface with VHB which has been holding fine. It's a quick and dirty solution and there's some weird imperfections on the model because of how I extended it but it worked and is sealed inside the housing so I didn't bother to fix it. STEP file is included if you'd like to make a less janky derivative but this one got the job done for me.
