It is quite common to use some sort of 3D printing technique to create who knows what, and its various uses and applications are still emerging. Whether you want to carve out a 3D gun for playing over the weekend or you need a prototype to present a concept, 3D printers can be used for a variety of purposes.
If you are a 4x4 enthusiast or happen to have one in your life, odds are they would freak out if they saw what the latest in 3D printing had to offer.
The YouTube channel, 3D Printed Engines, have created a range of working models of 3D car engines, differentials, and transmissions. The end product of his 3D printing is both mechanical and artistic, just like some kinetic art.
The 3D printed Toyota 4WD Transfer Case Model, including the double gearbox, is a gear-driven transfer case which is popular among 4WD (four-wheel-drive) enthusiasts due to its strength, as well as its ability to attach another low range gearbox to get an ultra-low final drive ratio.
The printed double gearbox is fully functioning and can be seen in the video below.
