Make it Yourself: 1000 Useful Things to Make - A free book by NODE that houses guides on how to make an extremely wide arrange of common items, as well as how to make the tools to create even more
And a huge amount of items are "3D print this". This was disappointing. It's basically just a curated printables list. The stuff listed looked really well designed, but I was hoping for more of a "here's simple machines and tools to build when you don't have access to better equipment"
In a way, or at least in spirit, it's similar to the Whole Earth Catalog: Access To Tools, which is something NODE has mentioned enjoying before. So I suppose it is more of a catalog. It is unfortunate it's reliant on having an internet connection to be used, but still, quite an impressive collection.
