This is my Oscar model remix. I've made original stl mesh (2MB) much denser and polished (25MB).

Treat yourself with an Oscar because you can with 3d printer :-)

Use Prusa Slicer cut tool to make 2 pieces.

Suggested print settings
For Oscar:

• 4 perimeters
• 15% adaptive infill
• Hilbert Curve top surface

For base:

• 3 perimeters
• 15% adaptive infill

Gold filament: I find Sunlu Light Gold giving best results. 

If you want plate with sign, use 35x70x1mm box and design it yourself in Tinkercad. Make main signature letters 8mm high and additional if needed at least 5mm to be visible.
I've used Prusa Slicer color swap to make it awesome. Take it of the printer bed right after printing and wrap it around the base. After a short while it will stay rounded for glueing.
