Model Overview & Print Notes

Educational tool for roll center analysis This project is an educational tool designed to analyze and understand the roll center in double wishbone suspension systems, commonly used in RC car models and, at a conceptual level, in full-scale vehicles as well. The model allows you to visualize and analyze suspension kinematics, clearly showing how suspension geometry and pickup point positions affect the roll center location and its variation during movement. 👉 This is not a functional racing component, but a study and learning model. 🎯 Purpose and field of use This tool allows you to: 📐 Analyze roll center generation and movement 🔧 Study the influence of suspension geometry on vehicle behavior 🧠 Understand the effects of changing suspension pickup points 🎓 Support educational activities and technical self-learning Ideal for: Advanced RC modelers Vehicle dynamics and mechanics enthusiasts Students and technical hobbyists Not an official product and not affiliated with any commercial brand Not designed for racing use or as a track setup tool ## 3D Printing Settings 🧵 Recommended 3D printing material PLA The project is optimized for PLA 3D printing, which provides: good dimensional stability ease of printing sufficient accuracy for an educational tool High mechanical strength is not required, as this is a static analysis model. 📏 Printing tolerances and movement smoothness For proper functionality, it is essential that the 3D printer used maintains dimensional tolerances within ±0.2 mm. All moving parts are designed to be very free and smooth, ensuring accurate visualization of suspension kinematics and roll center behavior. If some joints or sliding parts are too tight after printing, it is recommended to: 🧽 use fine-grit sandpaper lightly refine the sliding surfaces avoid invasive modifications that could alter the original geometry 🔩 Hardware and assembly For fixing the tires/wheels, the following hardware is required: 🔩 M3 button head screw 📐 Length: 8 mm or 10 mm, depending on printed part thickness ⚠️ Important: Do not overtighten the wheel fixing screws. The wheels must remain free to slide, allowing them to correctly follow the movements imposed by the suspension geometry. Excessive tightening would compromise the educational purpose of the model.
