This is the Dog Tag base that I design in my video on making dog tags. In the video I show how to make this yourself in Fusion 360 and how to add designs on it, such as a relief like on a coin.

I printed these with the phrozen transform 5.5 inch option. I oriented it with one of the long edges attached to the build plate with no supports. But any high resolution resin printer should work.

The metal dog tag was manufactured by sending the final STL file to a metal's company in China.

In the video I also show how to create a relief and how to give it depth and detail.
