For a test of my Heated Build Platform with aluminum plate coated with Extra Hold Hair Spray I needed something very large to test with so I scaled this up and also thinned it out too.

Print both halves and glue them together for a very large coin.

Again I was just looking for the largest thing I could print to see if my hair spray coated heated build platform would hold on to something really large.

This thing is so large I'm thinking of making a derivative to cover ceiling boxes that are no longer used.
