Modeled this in SolidWorks and also converted one of my renders into an icon to use for my own Bitcoin file which I also included.

update: tried printing one and the details were much too subtle so I made the text a tad higher and split the model in half. I uploaded an STL of the new half and I'm trying a print of it myself now...
.
update2: tried the half scaled 110% better but made a new thinner half and uploaded it, I'm printing it now at 120% which gives it a 58mm diameter.
