Eyeglass Holder Model for 3D Print

I found my design pretty easy to make seeing as it is really just a bunch of shapes on each other so that part was easy. I was trying to make it look a little like a bear but it turned into looking like a bear/pig/robot mix thingy so as of now its just an odd ball with no real shape behind it. The part I struggled with was the size of it, I don’t know how big it will actually be when I print it (eventually), I honestly just guessed on the size so I may have to go back and adjust it once I do figure out what the proper size of it should be in real life. I tried to get my measurements as exact as possible, some might be slightly off but I think for the most part everything is even. It did not take me too long to put this together I just got lost like mentioned before in the sizing of everything, Either way I guess it doesn’t really matter as long as it can hold a pair of glasses up without a chance of them just falling off.
