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.
