I wanted to have a cup holder that I could use while just chilling on my Sofa and rest a drink down but didn't like the options out there. I just wanted something that could slip between two cushions and would hold my drink up. I decided to just design my own cup holder, just a simple one and nothing more.

Filament: Sunlu PLA
Nozzle: 0.4
Layer: 0.2
Infill: 15%
Brim: yes 5mm
