Building a Homemade Super Mini 4WD from Scratch: Design for a Single Loop Track#shorts

In my childhood, I used to admire those who owned super-fast 4WD cars. I hoped that one day I could create a sleek and stylish racing car to conquer challenging tracks. Recently, a sudden inspiration struck me, and I decided to fulfill that childhood dream by designing and 3D-printing a super mini 4WD track car using the bambulab x1c. My goal in designing this car was to allow it to navigate complex tracks within a smaller space. I wanted to create a car that could offer a variety of racing styles without requiring a large area. Additionally, I wanted the car to have ample room for modifications, providing an enjoyable experience of customization, such as changing tires and experimenting with different guide wheels. I also aimed for an aesthetically appealing design, including the incorporation of illuminated lights. I have conducted some preliminary tests on these elements, and I believe you can see them in the accompanying video. The basic structure of the 4WD car relies on a relatively simple circuit design, making it accessible for those familiar with basic circuitry. The car is powered by a rechargeable battery, promoting environmental friendliness, and the convenience of a type-C interface. The redesigned mini-track vehicle is smaller, lighter, and faster, while also being safer, making the racetrack more space-efficient. I hope you like it.
