You need to craft it. There's a book called DIY projects in general store that contains that recipe.
The only craft book I see is the advance book and I have already read that. I am only at Year 2 summer 20.
The book won't show up on the store if you play older version than 1.02, I believe (that was a bug where you couldn't find DIY projects book anywhere so I added it to the general store stock later on)
Ok, I'm playing 1.0.0 still the Finn Beta
