Christmas coaster/trivet

3D Printed Christmas Coaster / Pot Holder with Integrated Heat-Sink Design Bring holiday spirit and practical utility together with this versatile 3D printed Christmas coaster. Designed with a built-in heat-sink pattern, it doesn’t just protect surfaces from warm mugs—it can also double as a lightweight pot holder for small hot dishes. Just pour water into the grid on top to turn this magnificent device into a portable heat sink! Worried about steam? This design comes with steam vents to let the steam out, but keeps the heat sink water in. If you fill the heat sink with water or another liquid, then it is recommended to waterproof the grid after printing with Modpog and use a water-resistant filament. The festive top pattern adds seasonal charm, while the functional geometry on top disperses heat more evenly than a standard coaster. Its rigid print structure keeps it stable, and the textured grip helps prevent sliding on smooth surfaces.Perfect as a Christmas gift, stocking stuffer, or
