For fun I decided to make a table fan. The casing is fully 3d printable.

To add weight the base has some space where I poured some concrete.

For the electronics, support for an RS-550 motor is planned.

To control it I used an arduino as a PWM, a mosfet and voltage modulators, but I guess anything is fine.

On the side there are 2 holes to be enlarged as desired for inserting LEDs or potentiometers and on the back there is a support for inserting a 14mm X 13mm current connector.
