Here is my homage to the 2016 Rio Olympics.
These are the official pictograms for the various games (some but not all).
The 2D drawings were converted to double sided 3D using Solidworks. Each medallion is about 1" x .75" and about 3/16" thick. Of course they can be scaled to any size before printing. They actually make great paper weights, or if printed in different colors used for good game of checkers.
For those wanting to download them, I posted them on Sketchfab:
