The summer might be coming to a close, but that doesn’t mean you can’t soak your friends and family in a water fight. Spray the day away with this 3D printed Manivelle Water Gun designed by maker Hassan Nasser. 

Many of us can recall our fond summer memories of neighborhood water fights, from the strong spray of a Super Soaker to the surprise splash of water balloons. While this summer season may be coming to a close, one maker named Hassan Nasser has shared an awesome 3D printing project that will keep you in the pool until the Autumn leaves have taken over.

His DIY Manivelle Water Gun is a crank-based water gun that is entirely made from 3D printed parts. It uses a crank mechanism to spin a fan and shoot out water from the head of the device. It doesn’t look like your average water gun, instead resembling some kind of leaf blower or handheld vacuum cleaner.

It’s unique, easy to make, and most importantly, will provide immense enjoyment for the waning summer days. Let’s take a closer look at this project and how you can make one yourself.

3D Printed Manivelle Water Gun: What You Need & How to Build it

In order to build this crank-based water gun yourself,  all you need is a 3D printer, some filament, and a hot glue gun. The designer has shared the STL files and assembly instructions on Instructables, where he details the role of each 3D printed part. Since this project will come in contact with a fair amount of water, it’s probably wise to use a material like PETG.

The Manivelle Water Gun consists of various 3D printed parts, including the fan, base, cover, head of the gun, handle, and even a 3D printed screw. The maker mentions that a metallic screw can be used to maintain the strength and durability of the crank gun.

Nasser showcases the assembly process for the Manivelle Water Gun through a screenshot of his Tinkercad design. All you have to do is connect all of the parts using a hot glue gun.

It’s a simple and easy project that will result in a lot of fun for the whole family. It might not have the pizazz or spray radius of an original Super Soaker, it’s still a great example of how 3D printing can lead to some fun in the sun. You can learn more about this project on Instructables, or download the STL files directly from MyMiniFactory.
