Don’t throw out those used coffee grounds—use them for 3D printing instead Any object you create can be thrown back into a coffee grinder and reused on a new object.

If you want to make precise mechanical parts, don’t use Blender. Blender is a tool for organic and sculptural forms. Want to print out a plastic tree? Blender is a great tool.
