Did you

- Make them in a single game day (starting at the start of the gameday)

- Get all the items finished too?

I am not sure what is the actual trigger, and this is (so far) the best which people have come up with. It could be that you need to make more difficult items or create 30 different type of items to get this. Keep me posted if you find out anything more.
