SummaryInspired by http://www.thingiverse.com/thing:375081. I designed my own to make it sturdier. Designed by creating an SVG in Inkscape from a borrowed web image and imported into 123D Design as sketch then extruded, keyring added and refinements made. Would love to give credit but this image is floating all over the web (especially tattoo web sites) without any reference to the original owner/designer. SVG en 123dx files included for you to remix at your hearts content :) Enjoy!Print SettingsPrinter Brand: RepRapPrinter: Prusa i3Rafts: NoSupports: NoResolution: 0.2Infill: 20%Notes: The white one in the pics printed beatifully with FormFutura Premium PLA Frosty White
