This is a remix of lzyperfection's Captain America shield, wherein I loaded the file into Blender, scaled up to about 19 cm in diameter, then split the model into separate parts, one model file for each color on the standard shield.

The "red" file contains the outer rim and inner ring. The "silver" file contains the star and the ring between the two reds. The "blue" file of course contains the central blue circle behind the star.

In the red and silver files, there are pieces that are suspended in mid-air. This is deliberate, so use your slicer's plater to "split" the pieces and force them back down onto the plate. If you don't, nothing will go wrong. You'll just end up with a lot of excess support material to fill in the air under the parts. :-)

Post-Printing

I've left a 0.1mm gap between mating faces, but it's a tight fit, so you'll want to shave/sand things down a bit more.

How I Designed This

Just pulled the model into blender, cut it apart, and exported.
