Making Smallest Bubble Blower Machine Using 3D Printed Parts

Hello friends in this Instructables i will show you how to make express bubble blower machine at your home.

This is a party essential and if you are building this definitely is an eye catcher.

The best part about this tiny yet fully functional bubble blower is that almost all the parts are 3d printed except the electronics.

Even though i mentioned the word tiny many might have already judged its performance! I would say that this is almost similar to the large sized ones out there.

This express bubble maker machine consumes less power and its powered by a single battery that can run for hours before the next charge.

Just by carrying a couple of batteries this will last forever i would say!

How cool is that! This device is portable and like you can see this can be carried around wherever you go.

I would like to say the best part about this bubble blower is the design!

Now you might have already asked yourselves, Why you used semicircle bubble maker instead of the regular full circle sized bubble maker?

There is a reason for that

The full circular bubble makers consumed more bubble solution and upon increasing the speed of the bubble making part it generated lots of foam on the tray that led to spills.

Solution was simple, Cut down the size of the maker and almost all the issues were brought down.

There is an option to increase the speed(pwm speed controller) and you can adjust the bubbles making speed at your control.

Did you know the other best thing here?

I wanted to make this bubble maker as efficeint as i could keeping the budget of most hobbyists on my mind.

I used the coreless dc motor to blow the air, and this works the best.

Bubbles will be blown using the coreless motor with propeller attached.

By the way this motor blows air backwards hence the motor was placed in the reverse order as you can see.

Now you might have decided already to build this and im almosg glad that you made up your mind and in return i will be giving you all the details by which you can make this at your house withiut breaking the wallet.

Here are the materials that i will be using to make this bubble maker

Micro Servo(Modified to rotate 360 degrees)

Coreless DC Motor

Propeller for Coreless Motor

PWM Speed Controller

Battery Holder

18650 Battery

Screw Driver

3D Printer

PLA Filament

Tinkercad

Cura or any other slicer

Super Glue

Bubble Solution

Place to produce bubbles

If you buy from my amazon affiliate links above i will get small percent of sales at no extra cost to you this will support me to come with new ideas

I made the design using Tinkercad, I started by taking rough measurements considering the size of the servo motor and the battery.

My main goal was to make the frame as small as possible while achieving the maximum efficiency of producing bubbles.

Also the parts need to be strong, keeping all these factors in mind i came up with this design and you can find them in the below step.

Use them, Modify them and let me know if you could beat me in the game of this bubble making! Just kidding.

You can add different parts to the same model but keep in mind that the servo part is designed taking the actual servo of sg90 motor.

It took me quite a while to come up with this final design and later i exported them to the cura slicer and you can see the settings that i used here to print the part.

Later this was imported to 3d printer for printing.

I made use of different colored filament to print these parts, you can do the same or go with single color.

After you have done the printing we can work on the electronics part that will give life to this 3d printed parts.

There is no much to discuss about the circuit, the circuit is simple and very easy to make and even a beginner can do this in no time.

To control the speed of motor i will be using PWM speed controller.

The coreless dc motor and the micro servo modifies to full rotation is connected to the PWM speed controller board M+ and M- respectively.

I recommend using one controller because it gives out the good results.

Here the rotation direction of bubble maker is not important but the direction of rotation of coreless motor should be taken care of since the propeller can produce air flow in one direction only.

Both of these are connected to one terminal only and the best part here is when you increase the bubble maker speed the coreless motor speed also increases thus increasing the air flow to the bubble maker to blow more and more bubbles.

After you make the circuit make sure to test it, keep in mind that you are using the rechargeable 3.7v battery here.

The PWM controller can take upto 6v, But here im using only 3.7v and there is nothing to worry about the performance.

I will start by gluing the servo to the frame of 3d printed part that has the storage tank for soap solution.

Use tiny amount of glue to attach these 2 parts and after it is dry i will be using the extension gear, now you may ask why this gear?

This is for stability, since we are using the half circle or the semicircle the machine becomes unstable at high speeds so with this we can balance.

Add the bubble maker part to this gear using the super glue as shown in the steps above, allow to dry completely and also check for the proper alignment.

Now attach the coreless motor to this tube using the superglue.

This will be connected to the side of battery holder and now the connections will be made as follows

Using this bubble blower is fun and i would say its the best moment you will have since you can see your imagination coming to life and doing great things.

Some time back your idea was sitting as a design inside a computer, now its a device that is blowing bubbles how cool is that!

I had some soap liquid from my dishwasher bottle, you can either use this or if you know how to make solution for bubbles you can use that too.

Pour it to the storage tank upto full(make sure you will not spill) and then save the solution for later since if you increase the speed the solution will be used up soon.

Now start the pwm speed controller, in my case the coreless motor starts first and as you increase the speed gradually the bubble making servo starts.

Increase the speed untill you see the bubble formation and adjust the speed as your bubbles needs!

Since im using the 2400mah battery the battery lasts for a few hours at the normal speed.

If you run out of solution, pour it from the reserve!

This is all about this bubble maker machine, So when are you going to build this?

Let me know, and like always there is a working video given in the next step.

Here is a video that you must consider watching if you want to check how much bubbles this small device can produce.

This video also has the slicer settings and the build tutorial from the very beginning

I hope you will try to build this project, and like always there is support from me if you feel struck at any phase of the build.

So lets conclude this project, and i will be very eager to check how well your project came out.

Thank you for reading till here and have a happy build :)
