Shutter Shades DIY Glasses now in wood

Made for 1/8" thick material.

Both glasses styles are identical in terms of scale, yet they each fit my head differently. So I guess sizing depends on luck.

That being said: they both fit me normally/snuggly and I consider my glasses width to be on the "small" side. If you consider your head to be "large", you might want to scale up. Which I think is odd because I already scaled up the original file by about a quarter inch, but it's your call. Best of luck to you!
