This 3D model pays tribute to the iconic high-revving Toyota 4A-GE 20V engine.

Model Overview

Based on an original 3D scan, this model has undergone several modifications:

  • Cleaning and remeshing
  • Geometry correction and simplification
  • Surface refinement for FDM printing
  • Wall thickness adjustments
  • Overhang optimization
  • Rebuilding structural elements

Additions include:

  • Separate intake trumpets
  • Exhaust headers
  • Display base
  • Modular assembly structure

This is not a raw scan upload; it is a mechanically adapted and print-optimized version.

Printing Specifications

  • Layer Height: 0.2 mm
  • Infill: 15–25%
  • Supports: recommended for exhaust headers

Material Recommendations

  • Silver filament for headers
  • Black for cam cover
  • White/Grey for block

Resin printing can provide higher detail if preferred. Note: Glue is required for final assembly. CA glue (super glue) is recommended due to fine components and printer tolerance variations.
