This is a multi-component print that can be assembled into a set of steampunk-style glasses frames which snap-fit over standard safety glasses.
I made my set to wear to the FIRST Robotics Competition 2017 game, which has a steampunk these.

Note on wearing: These frames are designed to snap-fit over regular polycarbonate safety glasses. The pressure of somebody wearing them is enough to make sure they don't snap out, but if you want, they can also be attached with a wire "twist tied" across the nose bridge in the middle. There are tiny holes in two of the triangles in front you can use to hide the tips of this wire.
There are 18 different pieces, so close-fitting parts may require some playing with settings - If everything's oriented properly in your slicer, every part can be printed without support material. I used rafts for most parts, but that was primarily due to an uneven print bed. A raft is really only necessary for the tall narrow parts like the two 'spikes', which need to be printed upside down. I got almost all of the parts to snap fit, but the three "hex" parts which hold up the wire ring holder needed a bit of hot glue as filler.
