Hydra Medallion from the Captain America movie
by BradDudenhoffer, published
A simple 3D extrusion of the Hydra logo from the Marvel universe as seen in Captain America. It may be a little thin for some uses but I included the skp so you can scale it to taste.
Printed full-scale it is 7.5cm across and it scales up and down nicely. If you go much less than 50% you will start to lose detail.
