山本トロン (YamamotoTron)

3D model data in OpenSCAD format of "山本トロン" (Yamamoto Tron).

Overview

This is a 3D model data of the "Yamamoto Tron" in SCAD (OpenSCAD) format, written for generating STL data to 3D print it. "Yamamoto Tron" is a 3D model introduced in a legendary book "パソコンによる3次元グラフィックスの実際" (The art of 3D graphics by personal computers) written by Tsuyoshi Yamamoto, a professor at Hokkaido University, in 1983.

How to generate STL?

This is compliant with OpenSCAD 2015.03-2. You need to install OpenSCAD first.

1. Open the code with OpenSCAD.

2. Set the parts to show.

   The model consists of three parts. To generate buildable STL data, you need to generate those parts one by one. Set the parts_to_show parameter to select a part to show.

   For example, to show only the front tire part, set it as

   parts_to_show = [0, 1, 0];
   

3. Set the scale factor.

   The default real size is around W161mm x D101mm x H85mm.

   If you want to scale it to save cost or need a bigger model, set the fscale parameter.

   For example, to reduce the size by half, set it as

   fscale = 0.5;
   

4. Set the rendering precision factor.

   The default rendering precision is optimized for a real-time preview. The better precision is recommended for STL data.

   Set the prec parameter as 0.1 or other.

   prec = 0.1;
   

5. Render and export as STL.

   Render polygon mesh of the model by pressing F6 or selecting "Design" > "Render". After rendering, export the mesh data as an STL file by selecting "File" > "Export" > "Export as STL...".
