This is a coaster that I designed back in November when Fallout 4 came out, This was printed and moulded to be cold cast in aluminium powder to give it that authentic metal look which can be seen here https://www.youtube.com/watch?v=HT6rIFAqnKE

*Updated the file, it should now be scaled correctly and ready to print
If the file does not open on your slicer then download the 'cog' file and scale to 101.6 mm diameter
