V8-Engine Paper Model
I'm no mechanic and I have very little interest in cars, this is evidenced by the state my car is in, but this papercraft model of a V8-Engine is the nerdiest thing I've seen all day. This guy took over a year to design and construct the model, and the website has a number of fantastic images and videos showing it off. Yes, the videos show the engine in motion!
This “V8-Engine” has semi-realistic exterior and interior detail. It is made entirely from paper (except a motor, a battery holder, a few plastic tubes and electrical wires). No paint applied. It looks pure and elegant. Various shadows created by different light sources make the appearance more 3D. Many moveable parts include a compound crankshaft, a rapid cooling fan, 8 rods, 8 pistons and a complex compound gearbox etc. It is handcrafted with ruler, white glue and X-acto knife. It took approximately one year to design and construct. Each part is precisely made (for instance, the five separate bearings need accurately alignment). The reinforced structure applied in both inside the body of engine and the stand (most of them can not be seen). The reinforced structures make it very rigid and keep the pieces in the accurate positions.
