The initiation of this project came from the desire to make a toy using a 3D printer. For some reason, air conditioners are devices that my son is very interested in. Therefore, I decided to design and make an imitation of device, which looks similar to the external unit of the air conditioner.
This toy is basically a fan. It has two switches: ON / OFF and six-position switch to control engine speed. It is powered by two AA batteries or rechargeable batteries located in the step-up converter. Currently, the physical product is being refined in terms of aesthetics and decoration.
