I am not sure how many of this type of sofa there is out there and I don't know if the dimensions of the cup holders are consistent.  However; if you have one of these sofa that has these cups holders you probably know that they work for cans and cups, but they are horrible for anything with a handle or wine glasses.

Here is an insert for the sofa that creates a flat tray for coffee cups, wine glasses or anything else.  It is a little small, but it is the biggest I can do until I get my XL.  : )

PETG at 25% infill seems to work nice.
