Designing a Simple 3D Printed Rubber Band Car Using Autodesk Fusion 360

"Designing a Fun 3D Printed Rubber Band Car with Ease using Autodesk Fusion 360" is a step-by-step tutorial that shows how I created, printed, and assembled a simple rubber band powered car for kids and grandkids. This compact "pocket size" car may not be the fastest or longest distance runner, but it's perfect for table top racing, extremely durable, and comes in two modes: "power" and "coast". Power mode is when the car unwinds the rubber band from the axle. Once the rubber band is completely unwound, it disconnects from the axle allowing the car to enter coast mode for extra distance. The symmetrical design of this car requires only eight 3D printed parts (two chassis sides, two axles, and four wheels) yet all these parts are based on just three unique designs (chassis, axle, and wheel). The best part is that all parts are small enough to fit on most if not all 3D printers. I've included a detailed step-by-step video of the design and assembly process, the Autodesk Fusion 360 cad file "Rubber Band Car v1.f3d" containing the design (familiarity with the Autodesk Fusion 360 environment is highly recommended), and all .STL files required to print the car. As usual, I might have missed a file or two or something else entirely, so if you have any questions please don't hesitate to ask as I'm known to make plenty of mistakes. Designed using Autodesk Fusion 360, sliced with Cura 3.5.0, and printed in PLA on an Ultimaker 2+ Extended and an Ultimaker 3 Extended.
