Quanum v2 Goggles Glass Lens Mount from Harbor Freight

This is an adaptor to mount a glass lens in the Quanum V2 goggles. The Fresnel Lens they come with is complete garbage. It is truly much, much better with this upgrade, I promise.

You can get the glass lens on harbor freight for a few dollars.

The little tabs will need a bit of support when printing. They are the trickiest part. If they break off, you might as well just glue the lens in and call it good.
