Acrylic Desk Fan (customizable)

Introduction: Acrylic Desk Fan (customizable)

Here is a neat little desk fan for those who only have a tight desk space at home and need some fresh air to keep them going. it's small, customizable and works by usb, so no batteries required, hardly takes any charge from your computer and stays running s long as your computer is on!


- solder iron

- line bender

- solder wire

- A usb fan kit ( you can find this on, stock code: 2162)


1 x 90mm Blue Three Blade Propeller.

1 x Low Inertia Solar Motor - 1820 RPM.

3 x USB Power Lead.1 x PCB Mount Slide Switch.

1 x 15 Ohm Resistor.

1 x Resettable Fuse 0.05A 60VDC.

1 x USB Fan Kit PCB.

- some acrylic

- a laser cutter or jigsaw

- epoxy glue

- two 13mm spacers

- four 5mm diameter screws

Step 1: Step 1: Assembling the PCB

NOTE : please read what is on the PCB before attempting to solder anything, there is an important not on the PCB, i take no responsibility for any mistakes.

The kit comes with a PCB, resistor, switch, motor, USB wire, and a fuse. What is needed from you is a solder iron and solder wire. All you need to do to assemble is to place all the components onto the pcb (note: the pcb shows with letters and signs where everything needs to go, and remember not to solder on the wrong side). Now after placing everything in it's right positions, go ahead and solder them onto the PCB.


1 - switch: there are 5 holes in PCB on one side, take the switch and place it in the holes ( the switch has 5 legs) and solder it into place.

2 - resistor: there is a square in the PCB that reads R1 which is the place for the right place for the resistor, this box has 2 holes for the 2 legs of the resistor, and it doesn't matter which way you put the resistor.

3- fuse: there is a circle drawn on the face of the PCB and that is the position of the fuse, it has 2 holes on either sides which are where the legs fit it, again, the direction of input doesn't matter.

4- motor: the motor has 2 wires coming out of it, red and black (important to remember that red is positive and black is negative). If you look at the PCB, there is a square that has the words "MOTOR" printed on top of it and on the sides of the square, there are the words, "red" and "black". Then finally outside of the box, there is a hole, and that is where the wires should be threaded through from the bottom to top, and place in the right holes inside the square, then soldered into place.

5- power supply: much like the motor, this has 2 wires, red and black, and the second box on the PCB, reading "POWER" is where the wires should be placed. again, there is indication on where the wires should go, outside of the box, there is a hole, and that is where the wires should be threaded through from the bottom to top, and place in the right holes inside the square, then soldered into place.


Step 2: Step 2: Designing the Shape of the Body of the Fan

You can choose any shape for your fan as long as it has a 6mm diameter hole for the motor and the holes for the PCB that i have shown in my drawing and commented on, and as you can see, there are also measurements.

As I said at the beginning this is fully customisable, you could use 2 pieces of wood as the body of the fan ( one of them having an angular cut so it turns out less than 90 degrees). Or you could even use 2 pieces of acrylic stuck together in the same fashion as the one i mentioned before. it doesn't have to be acrylic line bent, it is customisable, meaning it should suit you.

The pics show what i did for mine:

Step 3: Step 3: Assembling the Whole Fan

Now all we need to do is to assemble the fan's PCB with the acrylic design of your choice by using your 4 screws and your 2 12mm spacers the pics show how it's done. Finally, glue the engine to the design so that the rod is now sticking of of the hole, stick it using epoxy glue.
