Testi-cooler

For all who asked, Here it is. The in-waist band cooler of my own design for the masses.
I used a 5v-24v step up converter, a mini switch i had left over from game boy builds and a micro usb break out board from the same. it utilizes a power bank to power to reduce weight on the unit itself and works quite well. Please feel free to remix and show me your builds please. Thank you and enjoy.

P.s, I know my file is garbage, I am lazy and model to get to the end quickly. Please don't critique the model, improve and share alike. :)
