Convertible Racing Car

• Modular Structural Design The model is built using a split-part assembly approach, consisting of four major independent components: the body, windshield, rear wing, and gear-driven wheels. The wheels are secured with four M3 screws, allowing them to roll freely once assembled. Each part features precisely designed alignment slots, eliminating the need for complex supports during printing and enabling easy disassembly and reassembly. Multi-color filaments can be used to differentiate the body, rear wing, and wheel modules.

  

• Design and Assembly Features The car adopts a retro convertible sports car aesthetic, with rounded body lines complemented by an open cockpit. A raised rear wing enhances its sporty appeal. The wheels feature anti-slip tread patterns for smooth rolling. The entire structure is modularly assembled, allowing the windshield and rear wing to be detached and replaced individually. Its simple yet playful design makes it highly engaging for interactive assembly.

  

   

• Educational Value This project offers hands-on practice in parametric surface modeling, screw fastener assembly, and tolerance design. It covers the full workflow from 3D modeling and printing to manual assembly. The finished product can serve as a desktop display piece or a children’s craft toy, making it ideal for maker education and helping learners grasp fundamental mechanical concepts such as fasteners and detachable structures.
