This is a coin that is meant to test a 3D printer's capabilities. It has a distinct pattern on the coin that varies in height. All of the small geometric shapes created by the varying heights on the coin make it perfect for gauging the accuracy of filaments and programs.
The coin is 6 centimeters long, 6 centimeters wide, and 0.9 centimeters tall
