From Roosterteeth's hit series RWBY. Cosplay as Ruby Rose by 3D printing these STL files. Included is the cross worn on her belt in the Red Trailer, the rose emblem worn on her belt (vol 1-3) and cape (vol 4-6), and the cross pins worn on her cape (vol 1-3).
The cross pins have slots in the back for the tack portion of a butterfly clasp to slide in. The rose emblem does not. You'll have to glue something to clip it onto your cape.
