How to Make a Manivelle Water Gun

Manivelle (Crank) Water Gun is a new design of water guns that is characterized by the attractive view and in the fun that is created during water play. This water gun is a 3D printable object, so in this instructable, you will follow the designing of the different parts of the manivelle water gun.

This water gun depends on the mechanical motion of the hand to operate.

Step 1: Designing

Tinkercad is a very easy application to design a 3D printable object.

You can view it on Tinkercad: https://www.tinkercad.com/things/dspXTLUMqDF#

You can view it also on my minifactory: https://www.myminifactory.com/object/3d-print-wate...

In the upcoming step you will use a 3D Printer to print the different parts of the water gun.

Note: In my water gun I print each part separatly and then I gather them up using a glue gun because of the range of printing of my printer.

Step 2: The Fan

Download the file and print it.

Stick this fun in the screw through the center of the base part.

Step 3: The Base

Download the file and print it.

This part where the water circulate to be shoot out.

Step 4: The Cover

Download the file and print it.

This part that covers the the base part of the water gun.

Step 5: The Head

Download the file and print it.

Step 6: The Junction Part

Download the file and print it.

This part that connect the handle with the hole body of the water gun.

Step 7: The Handle

Download the file and print it.

Step 8: The Screw

Download the file and print it.

Note: you can replace the 3D printable screw by a metallic one to maintain the strength and the durability of the water gun.

Step 9: How It Should Be

View this 3D design to gather up the different parts.

Step 10: Gathering

Gather all the parts together by sticking them using a glue gun.

Step 11: The Final View

Step 12: Have Fun !!

I have tried to print this and found that most (all) parts needed to be rotated on the Y axis by 90 degrees. I was unable to print one part because no surface was parallel with the bed, no matter what axis I tried to rotate. It may be that files got corrupted somehow. I wonder if the author can review the attached screenshot for the head (head1-1.stl), which is from my Prusa Slicer and comment? The screenshot shows the support structure needed for printing the head because it is at a non-parallel angle to the bed. Perhaps the author can regenerate the TinkerCAD files. I'm very interested in completing this project!

This looks super cool. Can you share more about how it works? How do you load it? How long until you need to reload?

[Hassan Nasser]

Thanks,

It works by putting the base part of the water gun in water(pool,...) and then start to move the crank in a circular motion that pushes the water out, and it doesn't matter about reloading as you setting the base part (where the fan is) in water.
