What do I need to do to get the "Craft Master" achievement? The full list is here I've produced them all, what's missing?

Most people agree that hoppers are a bit disappointing, so I have an idea to fix that. Introducing, The Out-Hopper It's just like a(n) (In-)hopper, except it takes things out rather than putting them in. I do think that making the hopper two-way would be a bit overpowered, so this is my fix...
