Howdy. I know you all yearn to wear something sweet, metal, and culled from the oceanic depths of the oilpunk masterpiece Bioshock. This is your brass opportunity as I've converted its officially kickass logo into a 3d file for which to use, abuse, and hold up pants. It's a belt buckle. The versions I've done are in bronze from a cnc cut wax model (carved with a 1/8in 15deg inc taper profile tool) and a Zcorp 3dprint. It's pretty fine on the detail end of things so you might want to scale up if you're gonna go for a FDM.
I also have to thank the lovely and talented Meredeth Wrinkle of TechShop fame for photographing the Zcorp version of this project and being an essential supporter. I couldn't be holding this lovely little trinket without her constant support.
