My need was to have a holder for glasses, where I can get the glasses fast in and out, since my use is usually for just 30 seconds. Also, my honeycomb wall starts to be pretty full, so there was no space to attach glasses to any other posture.

I have been postponing this for over a year now, searching for inspiration what kind of holder I would make. All my ideas were so complicated that the work seemed too much and finally I just thought that I need something right now and this is the work of 10 minutes. Those glasses frames are 49mm tall and about 5mm wide and they fit perfectly.

Edit (before submitting): Aaaaand when putting that model up into Printables, I thought of simple way to make it a bit prettier. The finger model took an hour of designing. Both models are included, you decide it you want to go with simplistic Scandinavian design or ancient Roman design.
