Fusion 360 Designer Needed — Custom Raspberry Pi 5 AI Companion Enclosure (Echo Show 5 Style)

Summary
I am building Gigi — a personal AI companion device powered by Raspberry Pi 5 that sits on a desk like an Amazon Echo Show 5. I need an experienced Fusion 360 designer to take my existing script-generated prototype and produce a professional, print-ready STL with correct tolerances, clean geometry, and proper fitment for all hardware components.

What I already have:

Complete hardware specs and datasheets for every component
Echo Show 5 silhouette as design inspiration

What I need you to deliver:

✅ FDM print tolerances (clearances, snap fits, screw holes)
✅ Ensure all hardware fits correctly — no interference, no gaps
✅ Speaker chamber walls with proper acoustic separation
✅ Clean two-part split: Main Body + Back Cover Plate
✅ Export two print-ready STL files (body + cover) optimised for FDM printing
✅ STEP file export so I can edit later

Hardware to fit inside the enclosure:

Component
Raspberry Pi 5 8GB
WaveShare 7" QLED Touch Display 70H-1024600
Zebronics Zeb-Pluto 2.0 Speakers
CMTECK USB Conference Mic
Raspberry Pi Camera Module 3
