Couch Can Holder

thingiverse

This is a handy can holder that fits snugly under your couch cushion, providing a convenient spot to set cans in place. It's perfect for situations where you need a reliable surface but don't have one nearby. You can easily add extensions if the standard length isn't sufficient; however, be aware that tolerances are very tight, so once an extension is attached, it's likely to stay put securely.
