Cupholder

First time posting and first time doing 3D modeling or printing after purchasing a printer less than a week ago. A friend had limited space in their bedroom and no space for a nightstand with a desk across the room. Leaving no ideal spot to leave a glass close to bed. So I designed this to slip between the mattress and box spring so a glass or bottle can sit right next to you as you sleep. Two sizes are modeled here. V2 is for up to a 32oz bottle. I used tree supports when printing and turned out great. Please let me know if you have any suggestions to make this an easier print or improve quality. Let me know how your prints turn out as I'm new to designing and printing.
