Gridfinity (4x6) Glasses Organizer Tray

Update (2025.06.01): Added a 4-bin version to hold larger glasses and/or cases. 

This is a 4x6 glasses organizer that is inspired by the stackable glasses tray that they have at optometry stores to keep orders organized. Since glasses didn't quite need the full 1x4 square gridfinity width for storage, I was able to squeeze 7 glasses slots in a 6 gridfinity space.

I've added 8U and 9U height options. The higher bin size helps if you want to stack another gridfinity on top without hitting the glasses.
