Made a Stargate Cartouche style keychain which has the Earth address on it. Got and used the glyphs from http://www.thingiverse.com/thing:1395681. Printed with Silver PLA filament from http://blueprinted.co/ .
The first file has the "Point Of Origin" Earth symbol on the bottom and the second on purpose doesn't.
Sliced using Cura.
Printed with PLA
