Bladeless desktop fan 3D model

This small device is a handy desktop fan that works without propellers. Thanks to its particular design does not require blades to works. Inside the base I decided to mount an 80x80x15mm PC fan; the fan draws air from the bottom of the base and pushes it into the upper ring creating an increase in pressure. Only the base file (003.stl) needs to be printed with supports. What you need to complete the assembly is: 1 x desktop pc fan 80x80x15mm. 4 x M4 x16mm screws. an on / off switch (21mm of diameter). Assembly: 1) Mount the computer fan inside the base using 4 M4x16mm screws. 2) Solder fan wires to a switch. 3) Insert the fan inner (001.stl) into the fan outer (002.stl), no gluing required. 4) Mounte the fan inner and fan outer on the base.
