The original model on Thingiverse was designed for Resin printing, and has very fine details in the text areas, which makes complications printing on FDM printers. Added supports as welll for the side and lower structures.

I've adapted this for 2 colours (raised text/image against the coin)

The text is still not ideal on a 0.4 nozzle, but when sliced for a .2 nozzle it's perfect. (.4 shown in photos)
