When did Diary of a Wimpy Kid do it yourself book release?

There is no official "Do It Yourself" book in the Diary of a Wimpy Kid series.

The series is created by Jeff Kinney, and each book is written and illustrated by him.

If you're interested in creating your own "Wimpy Kid" style book, you could certainly do that! It's a fun way to be creative and tell your own stories.
