Elegant 3D-Printed Wall Key Holder

I’d like a beautifully refined design for a car-key holder that can sit proudly on a wall.

Scope
• Produce a complete 3D model ready for FDM printing.
• Optimise geometry for clean printing: sensible wall thickness, fillets instead of sharp overhangs, and mounting points for screws or a weighted base so it can hang.
• The cavity should comfortably fit modern key fobs while keeping the overall profile slim and sophisticated.

Deliverables
1. Print-ready files (STL or 3MF) plus an editable source file (STEP or similar). Preferably editable in Fusion 360
2. A quick render or screenshot showing the holder so I can visualise the final look.
3. Overall Dimensions (Approx): Length(X Axis): 330MM x Breadth(Y Axis): 220MM x Height(Z Axis) : 30MM

Acceptance
I will test-print the file; it should print without major supports, and all the text and car logo should be crisp and clear. assemble in one piece, and securely cradle the car keys without wobble. If it passes that functional test , the job is complete.
