This is a relief pattern of the Lion Rampant printed as a single part.
It is printed in two colours, but you can do this simply by pausing the print at about 80% (or when it starts to draw the lion and frame), and changing the filament.
I used transparent yellow for the shield and switched to transparent red.
To print 2 colours, you will have to pause the print at about 80% change filaments then resume.
I recommend watching it carefully and being quick to hit the pause when it starts to draw the lion.
I used 100% infill.
I scaled the model to 600% to get the keychain print in the photograph.
