I bought the HSS metric drill bit set from Lee Valley, which comes as simply a collection of loose bits. I decided to make myself a convenient holder for them.
The ZIP file contains all the DXF files with the outlines of the text. If you want to tweak the design, download the OpenSCAD file and the ZIP file, and extract the ZIP contents to the same folder as the OpenSCAD file, and you should be good to go.
