$5 Mini USB Fridge!

Step 4 Building the Fridge!

I used foamboard because of its ease in cutting with an xacto knife and its insular properties, and basically built a box around the heatsink using a hot glue gun to attach the sides and top, and then ran a line of hot glue along the seams to ensure an airtight compartment. The bottom piece is cut into two halves, with a square section cut out in the center to make room for the peltier unit. I then glued the two halves to the underside of the cooling heatsink, then glued the left, back, and right sides of the fridge, and finally the top. See the diagram below:

How thick was your foam board?
