Cupholder with Tray for Couch or Sectional

This is the first 3D print I've ever designed. My couch only came with 2 cupholders, and they are far away from some of the seats. I wanted a solution besides putting the cups on the ground, so I designed this cuphoder that slides between the cusions to give a stable base. The cupholder size, I based off of the existing cupholders in my couch as they are able to hold a full 40oz Stanley, additionally, I've added recesses on the side to support smaller coffee cups or cups with handles.

This model can be printed on the A1Mini in a single print. I would recommend supports for the insert. I've provided the openscad design which allows you to increase the size of the tray as well.
