edit: see my reply further down for a better version of this
Here is a pdf with tracing pages for the 2136 常用 kanji. It is unfortunately really big - 127mb or so.
I will share my code for it eventually, but I feel like it needs a rewrite first - to make it neater, to make the process faster (the pages took about five hours to generate) and to make the resulting SVG files that are then converted to PDF smaller. At the moment, every box / guideline / kanji on the page is drawn independently, which makes for very big SVG source files. It really should use a proper grid made of lines and SVG’s support for reusing elements.
