Embedded Captain American Shield book end.
took the floor design from (http://www.thingiverse.com/thing:171315/#files)
and shield from (http://www.thingiverse.com/thing:599204) to make this book end cover. I don't think it will handle much weight as is so I will glue it on to a steel bookend. I will try and add some damage to the wall and paint it before finishing.
