2018 New Years Shutter Shades

Getting an early start this year due to #[Makevember](https://twitter.com/search?q=%23makevember)!

2018 Shutter Shades designed from @drjames excellent [Customizable Shutter Shades](https://www.thingiverse.com/thing:1603773)

Upgrades for 2018:
* Bigger and better than ever!
* Now with snap-together frames (no pins needed)!
* Thin profile means less material and quicker prints!

By popular demand, I have made a 2018 version of the 2017 glasses, but with the thinner and snap-in frame.
