Imagine any chiral shape in 2-D, and its enantiomorph (a copy that is mirrored), perhaps a left and right swastika. Stretch both in the third dimension, just a bit to give them depth. Now stack them and glue together. This new 3-D shape is not chiral, because a 180 degree rotation is a symmetry, bringing one half into the other. This works for any 2-D chiral object. A 180 degree rotation through a third dimension is equivalent to a mirror in 2-D.
