My wife wanted a way to store her glasses and asked that I model this.
I modeled these to fit her glasses which are fairly standard sized. The glasses dimensions were 27x38x115mm.
I oversized the interior of the model to have the empty space be 34x45x113. I did these dimensions because it allowed me to insert 2mm EVA foam on every wall and the “floor” so as to not have to worry about her glasses being scratched when using it.

The model is designed to have two 20x3mm neodymium magnets glued into the back (flip their polarity when gluing them in).

The resulting model allows her glasses to slot in with little effort, and keeps them sticking out enough that they are easy to grab when fumbling in the dark (or because you aren't wearing your glasses).

The model could fit some other glasses without modification potentially, but if you'd like a larger size I could upload different sizes to accommodate so that the magnet holes don't get distorted. Just let me know what dimensions you'd like!
