How to make a fan

Let's make a simple fan.
You will need:
1. 3 V engine
2. Section on 2 batteries of 1.5 V. I took in the store "CHIP and DIP".
3. The switch.
4. Wire 15 cm.
5. Bobbins from fishing line or ropes, a jar from Polysorb, a jar of gouache.
6. Impeller from the cooler power supply.
7. Soldering iron.
8. Thermogun.
9. Screws 11 pcs. 2cm long.

1. Take bobbins from threads with a diameter of 5 mm and a height of 4.5 cm - from fishing line or cord.
We mark with a marker the hole for the switch and cut the hole with a nail scissors a little smaller than the size of the switch and insert the switch into the reel:

2. Now we form the fan frame: we will make 3 bobbins together and outline four holes for bolts or self-tapping screws with a marker on the bottom of the upper bobbins. We burn holes through the edges of two bobbins:

3. Using a lighter, we melt and clean the red wire from the section with batteries and attach it to one terminal of the switch, and to the other - the second red wire. To isolate the terminals from contact with each other, fill them with hot glue:

4. We fix the red wire to the plus + of the engine, and the black, respectively, to the minus of the engine:

5. The top can be made from a gouache box: on the lid with a soldering iron we form a hole for wires and 3 holes for screws. And on the box itself we cut a hole with nail scissors a little less than the diameter of the engine and place it inside. As in the case of the switch, it is possible to fill with hot glue from the outside for reliability.

6. We put the impeller from the cooler onto the cork, fill the voids with plasticine or fill it with paraffin, use a self-tapping screw or an awl to make a hole in the cork, fill it with epoxy or hot melt glue, and put it on the engine. If it is an epoxy resin - leave it to dry for a day and turn it on only after that!

P.S. Inside the canister from Polysorb (fan support) for the stability of the structure are old, outdated batteries.

    The girl is so scary that no one loves her and therefore she is engaged in any garbage?
    Why batteries, when everyone has a bunch of old, working, adapters for charging phones?
    Or does a girl take this ratsu out to the street so that people are neighing? Like it's hot to her, blows herself.

    Worse, something is very difficult to come up with. I can’t even think of such a hangover. I’m silent about a sober head.
