I am going backpacking to see the eclipse in a few days. I didnt want all our glasses getting smashed in my pack so I printed off this protective case. I am printing mine now and will upload a new version if it does not fit properly. It is designed to hold 11 glasses.

To fit them inside, fold ONE earpiece over and stack the glasses so the folded sides alternate.

print with the small sides down, no support.

I usually dont upload solidworks files, but I did here in case anyone wants to modify this. good luck and enjoy!
