I wanted to make a fan housing that would run off a USB cable. This is the first version and I want to start slimming down its profile and making it more visually appealing. I used a 5V motor (1.5 inch OD) and a lit rocker switch . Machine screws hold the pieces together while the motor is press-fit into the motor mount. I printed this on my Craftbot with PLA and medium quality settings. There is very minimal to no support for most parts.
