Introduction

This is the Bugatti logo or emblem or badge. The emblem is also called "Macaron". 
The letters are created in OpenSCAD without a font. I made the letters similar to the vintage old logo, because I think those are more beautiful.

3D Printing

The file "Bugatti_1.stl" is a thin plaquette of 106 mm wide. By adding two filament swaps, it can be printed with three colors.
With a layer height of 0.2 mm, the black and white color will be three layers each.

OpenSCAD

The source is a OpenSCAD script. OpenSCAD is free software: [https://openscad.org/](https://openscad.org/)

The script uses the BOSL2 library: [https://github.com/BelfrySCAD/BOSL2](https://github.com/BelfrySCAD/BOSL2)
The license of the BOSL2 library is: BSD 2-Clause

Custom text

A font can be used to create your own custom text with OpenSCAD. As far as I know there is no free font that comes close to the original vintage font.
The wrong font will make the emblem look bad in my opinion. The vintage Bugatti emblem is too beautiful to make a custom text.

However, if you want to make a custom text, then OpenSCAD can import a font file with the "use" command. Put the font file in the same folder as the OpenSCAD script file.

Other accurate Bugatti logos

User Chris made a accurate design with the vintage font: Bugatti - Logo. I got the idea for two filament swaps from him.

User GigaPenguin made a accurate design with the modern font: Tomica Bugatti Veyron Display Base. His design also uses filament swaps, but in a different way. He made many more car display stands for many brands.

License

The license for the script and the resulting stl file is set to CC BY-NC-SA, because it is a logo of a brand. It is therefor only for personal use. 
I don't mind if parts of the script are used for something else.

Disclaimer

I wrote the script in OpenSCAD to recreate this vintage logo as a fan, but I do not own the design. The brand name and the design are owned by the Bugatti Automobiles company.
