This cooling pad is designed to fit a 13 in MacBook Air but should work with other small laptops. I designed it to be as thin and light as possible while still providing adequate cooling capabilities. The fan I used is a thin 120mm fan linked below that I soldered a USB cable to. If you don't want to solder, I've also linked some USB to 4 pin connectors that will accomplish the same thing.

As designed, it will require a large printer with a build plate of at least 300mm. It is split into 2 pieces that are made to be glued together once printed.
