Use PNG in README.md files instead of SVG #2
Description
The SVG files created by CadQuery (for both parts and robots) are currently used in README.md files.
However this is an overkill as the files are big but they are only displayed as small images of fixed size.
An extra step needs to be added to create PNG files.
Once PNG files are used by README.md files, the SVG files of the parts could be removed.
