# bill of materials
1. switch
you can choose either [15mm circular rocker switch](https://www.aliexpress.com/item/4001332967504.html) or 7mm shaft toggle switch like [MTS-101](https://www.aliexpress.com/item/33012530737.html)
2. DC power connector
preferably, [5.5 x 2.1](https://www.aliexpress.com/item/4000648876487.html) connector. it is more common with 12V power supply.
3. 120mm computer cooling fan
i recommend 3000RPM at least. more RPM generally means more air pressure.
4. fan grill
you can print it, but i recommend using metal grill. it can be purchased under a dollar.
