Mini Car

thingiverse

Print a car along with its axles in one piece. This approach was inspired by observing other interlocking designs that can be printed without support structures. The model will produce a miniature car, including its axles, upon completion. However, some minor trimming using a knife may be necessary to separate the car and axle from each other. Testing has revealed that earlier versions (v1) of this design allowed the car to print successfully but the wheels failed to rotate when pushed across a surface due to insufficient gap between the axle and the car body, which caused it to rest flat on the surface. To address this issue, subsequent versions (v2) featured slightly larger wheels relative to the car's thickness. Further improvements were made in v3, based on gaining more experience with model generation. V5 represents a redesign, featuring internal wheels and a single long wheel for each axle, transforming the vehicle into a bike-like structure. The latest version, v7, utilizes a cylinder instead of a gear for the wheels.
