Have you ever wondered how cars manage to turn corners smoothly? It’s all thanks to a clever mechanism called the rear differential. Let’s dive into how you can build a 3D-printed model of this fascinating component!
First, you’ll need some parts, which you can order from a company like PCBWay. They can provide you with everything you need to start building. Once you have your parts, follow these steps:
Begin by sliding the gear onto the axle. Make sure it’s secure so it won’t slip off when in use.
Next, take the base plate and the ring gear. Screw these two parts together tightly. This forms the foundation of your differential.
Now, slide the side gear into its designated spot. Ensure it’s properly secured to avoid any movement during operation.
Finally, place the pinion gear in position. Once everything is in place, your gear set is complete!
It’s time to test your creation. When you rotate the gears, they should move smoothly and work together perfectly. If everything is functioning as it should, congratulations! You’ve successfully built a model of a rear differential.
But what exactly does this gear set do? Imagine your hand is the engine of a car, providing power to the gears. When the car moves forward, all the gears lock together, causing the wheels to turn in the same direction. The same happens when the car moves backward, but the wheels turn the opposite way.
When the car turns, things get interesting. If the car turns right, the gears allow the wheels on one side to move independently from the other side. This is crucial because each wheel travels a different distance when turning. Without this mechanism, turning corners would be difficult, and the axle might even break!
If you’re excited to try this yourself, you can download all the parts for free and use a 3D printer to create your own rear differential model. It’s a fun and educational project that helps you understand how cars work!
Gather your classmates and organize a 3D printing workshop. Download the parts for the rear differential model and print them using a 3D printer. Work together to assemble the model, following the steps outlined in the article. This hands-on activity will help you understand the mechanics of a rear differential.
Use an online gear simulation tool to explore how different gears interact with each other. Experiment with changing the size and number of teeth on the gears to see how it affects their movement. This will give you a deeper understanding of gear ratios and their role in the rear differential.
Form small groups and discuss how the rear differential contributes to a car’s ability to turn smoothly. Share your thoughts on why this mechanism is crucial for vehicle safety and performance. Present your findings to the class to enhance everyone’s understanding.
Create a simple gear model using cardboard and other craft materials. Design and cut out gears, then assemble them to mimic the function of a rear differential. This creative project will help you visualize how gears work together in a physical model.
Conduct research on the history and evolution of the rear differential and other automotive innovations. Prepare a presentation or report on how these technologies have improved over time and their impact on modern vehicles. This will broaden your knowledge of automotive engineering.

I ordered this from PCBWay, who sponsored this video. First, slide the gear onto the axle and secure it in place. Here is the base plate and the ring gear; I’ll just screw these together. This is the side gear; slide that into place and then secure it. Next, we have the pinion gear, and voila, we are finished!
Now, let’s do a quick test, and it’s working perfectly. That’s great! But what does this actually do? Well, this is the rear differential of a car. Imagine my hand is the engine providing the rotational power. When the car moves forward, all the gears lock, and the wheels turn clockwise. When the car moves backward, the gears are locked, and the wheels turn counterclockwise.
However, when the car turns right, the gears move independently, and when it turns left, the opposite side moves independently. This is because the turning circle is different for each wheel, and the speed of the wheels has to change; otherwise, we can’t turn corners, and the axle could break.
You can download all the parts for free and build this yourself using a 3D printer or through PCBWay.

This version maintains the original content while removing any informal language and ensuring clarity.
Gear – A rotating machine part with cut teeth that mesh with another toothed part to transmit torque. – In our DIY project, we used a gear to transfer motion from the motor to the wheels.
Axle – A rod or spindle passing through the center of a wheel or group of wheels. – The axle was crucial in ensuring the wheels of our homemade cart rotated smoothly.
Base – The bottom support of anything; that on which a thing stands or rests. – We built a sturdy base for our bridge model using wooden planks.
Plate – A flat, typically rectangular piece of material used in construction or engineering. – We secured the metal plate to the frame to provide extra stability.
Ring – A circular band, typically made of metal, used in various mechanical applications. – The ring was used to hold the gears in place within the engine model.
Side – The surface of an object that is not the top, bottom, front, or back. – We painted the side of the model car to make it look more realistic.
Pinion – A small gear or spindle engaging with a larger gear. – The pinion gear was essential for reducing the speed of the motor in our robot.
Model – A representation, generally in miniature, to show the construction or appearance of something. – We created a model of a suspension bridge for our engineering class.
Print – To produce a hard copy of a design or plan using a printer or similar device. – We decided to print the blueprint of our project to have a clear guide during construction.
Differential – A device that splits the engine torque two ways, allowing each output to spin at a different speed. – Understanding how a differential works helped us improve the performance of our remote-controlled car.
