Mechanical Squeeze Fan V1

Introduction:-

This is fully mechanical,  3d-printable squeeze fan. Its only need your hand no electricity and battry needed. I designed this from scratch using Fusion 360 to practice cad :-)

The Mechanics:

• Its a squeeze fan so its work with hand. First you have to squeeze the handle which is connected with a 48 teeth gear (rack-and-pinion).

• Now the 48 teeth gear connected with another gear's 24 teeth side (this gear have two different sides one 48 and other 24 teeth)

• this gear's 48 teeth side connected with another 2 side gear's 24 teeth (this gear's one side 24 and other side 34 teeth)

• now this gear's 34 teeth side connected with the main fan rotating gear's 17 teeth 

• all gears were connected with each other with the ratio of 1:2

• finally the fan started to give fresh air.

Hardware and bom:

• its have total 12 parts (one part need to be printed 2 times no extra others Thing needed.

3D Printing Instructions:

• you have to print all parts one by one with PLA OR PETG .

• The "stick_2" need to be print 2 times .

• recommend 20% to 30% infill so the gears are strong .

• This Mechanical Squeeze Fan no need any supports to print (I think).

 Assembly Steps:

1. first you have to take the "down_body" part 

2. then you have to assemble the "handle" and "stick 1 and 2" to the down body 

3. after it you have to connect the "gear_1" with the "stick_1"

4. now place the "gear_2" with the middle "stick_2"

5. place the "gear_3" with the last "stick_2". like this 

   

6. place the main gear in the top hole 

7. now assemble the "top_body" with the down body and at last add the fan to the main gear big stick thing like this 

   

now your fan is ready!!!

What I learned?

• I learned a lot. This is my 3rd time making a cad thing. 

• I learned about gear how gear work and some many more bla bla and also learned how to make it in fusion

• I learned about fan like how to make a fan the big round yellow part in fusion 

• I also learned to make honeycomb design 

• I'm really happy that i made this!!

 Some Bla Bla:

I love that how many things I learned by making this fan. I will make many more things so be ready and I'm also ready to learn more about cad and how mechanics works. Plz rate it out of 10 !!!

Credits & Inspiration

I already knew that the squeeze fan already made. I tried to recreate it so I searched one yt to see how the mechanism work and boom! I got a shorts where I saw the core mechanism. So I really want to credit

• This person's or yt channel's short video link: 

thank you soo much for this great idea!!
