4A-GE 20V Inline-4 Engine Miniature

📌 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 Store https://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 Store 🔧 Model 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 rebuilt In 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：0.2mm Infill | 填充：15–25% Supports | 支撑：排气头段建议开启 Material | 材料建议： • Silver filament for headers • 排气建议银色或金属色 • Black for cam cover • 气门室盖建议黑色 • White / Grey for block • 缸体建议白或灰色 Resin printing will provide higher detail if preferred. 如使用光固化打印，可获得更高细节表现。 🔩 Assembly | 组装说明 ⚠ Glue is required for final assembly. ⚠ 本模型组装必须使用胶水固定。 Due to fine components and printer tolerance variation, CA glue (super glue) is recommended. 由于结构精细且打印公差存在差异，建议使用瞬干胶固定。
