Cold Boxes - Insulated Containers

These containers are able to maintain a cooler temperature inside for longer than a common thermal bag. Due to the thickness of the walls and possibly the Knudsen effect created by the infill pattern, the interior remains colder. I designed three types of containers, and I used the smallest one to test the temperatures with a refrigerator thermometer. 3D printed cold box Fridge: 3 Perimeters, 15% gyroid infill.
