This is a simple coffee cup holder that I designed for my recliners. It fits a standard cup holder opening in a couch or recliner that will allow you to keep your coffee nearby and avoid accidental spills. The top opening is pretty wide to accommodate larger cups and the bottom is filled to avoid the cup tipping when placed in the holder.

Printed using the default Extra Draft (0.28mm) profile with 10% Gyroid infill. Print time is roughly 2 hours 30 minutes at Normal speed, but the model is simple enough you should be able to speed it up.
