Snippet about article just published:

Thingiverse user Eric Harrell has taken on the enormous challenge of designing and 3D printing his own Toyota 4 Cylinder Engine 22RE, which is fully 3D printed, except for some minor, small parts. While he points out that it required 60 hours to design, and over 72 hours to 3D print — what an incredible reward at the end. Featuring over 80 3D printed pieces, we were pretty blown away by this project. With his Thingiverse files, you can produce your own 3D printed, fully rotating model, with a working crank, pistons, and valve train.
