Various versions of a cup holder I am working on since we got a new sofa and the cup holders I had purchased for that didnt fit. Feel free to use any way you want and remix or adjust to fit your couch or sofa.

The latest version (v8) reduces material by using a hex cutout. I was able to print this with limited supports by tilting the model 45 deg on the plater and only using paint on supports for the top edge.
