Tired of your favorite mug or tumbler tipping over in your couch's built-in cup holder? Introducing the Universal Couch Cup Holder Insert! This 3D-printed accessory is cleverly designed to adapt oversized or undersized cups that don't fit securely in your standard sofa cup holders. Simply place the insert into your existing holder to create a stable, snug base that prevents tipping, spilling, and frustration. Keep your coffee, water bottle, or oddly-shaped drink safely within reach during movie night!
