Corolla Sail Panel Tweeter Pod

I already have an STL of the ’97 Corolla power-mirror sail panel; it’s the stock piece with no tweeter mount. What I need is for you to open that file, add a standard cylindrical pod for a Skar TX-T1 tweeter, tilt it 25° so it points toward the cabin occupants, and return a print-ready STL (plus a quick render so I can visual-check the angle).

A few practical notes:
• I’m brand-new to 3-D printing, so please keep the workflow simple—no exotic settings that only work on one slicer.
• I’m not sure whether my source STL is binary or ASCII; I’ll convert if needed.
• All factory mounting points on the sail panel must stay untouched so the finished part snaps in exactly like OEM.

Deliverables
– Modified, error-free STL ready for FDM printing
– One JPG/PNG render showing the 25° pod orientation
– Brief note on any print considerations (infill, supports)

If you’re comfortable tweaking OEM parts in Fusion 360, SolidWorks, Blender, or a similar CAD tool, this should be a quick, straightforward task. I’ll send the download link to the original panel file—and reference photos—once we get started. Below are stock examples of before and why I’m trying to achieve after. I’m not worried about the grill will have tweeters slid in from and glued from back.
