4A-GE 20V Inline-4 Engine Miniature

A detailed 3D printable tribute to one of the most iconic high-revving engines.致敬传奇高转速引擎的高细节可打印模型。 Introduction | 项目介绍This project is based on an original 3D scan model of the Toyota 4A-GE 20V engine, sourced from:Bremar 3D Scan Storehttps://www.bremar3dscanstore.com/cad-models/p/toyota-4age-20-valve-engine本项目基于 Toyota 4A-GE 20V 发动机的三维扫描模型，原始扫描来源于：Bremar 3D Scan StoreModel Modification | 模型重构与优化The original scan model has been:• Cleaned and remeshed• Geometry corrected and simplified• Surfaces refined for FDM printability• Wall thickness adjusted• Overhangs optimized• Structural elements rebuiltIn addition, I redesigned and added:• Separate intake trumpets• Exhaust headers• Display base• Modular assembly structure原始扫描模型经过以下处理：• 网格清理与重构• 几何修正与简化• 表面结构优化以适配 FDM 打印• 壁厚重新设计• 悬垂角度优化• 结构重建并新增设计：• 独立进气喇叭• 排气头段• 展示底座• 模块化组装结构This is not a raw scan upload — it is a mechanically adapted and print-optimized version.本模型并非原始扫描文件的直接发布，而是经过打印优化与结构重构后的版本。Printing | 打印建议Layer Height | 层高：0.2mmInfill |
