The great part about making a pair of goggles is that you have total control on how they look!
In fact, I found some great looking gold and natural PLA from Matterhackers.com
that looks like brass; a steampunk classic.
When you're ready, download these 3D models...
...and fire-up your 3D printer.
For reference, there is an exploded view
of the goggles over on Tinkercad.
