This lovely creation comes from a YouTuber Eric Harrell, who graciously shared its filesRolex Replica Watches
so you can print out your own version. Harrell has also 3D printed a replica of the entire driveline from a mid-1980s Toyota truck including its 22R-E four-cylinder engine, gearbox and transfer case.
Unless you work for Local Motors, you probably don’t have the capacity to 3D print a drivable car, but you can print a 35-percent scale replica of the Subaru’s well-known EJ20 flat-four engine. It’s fully functional, though obviously not powered by internal combustion, and thoroughly delightful.

Besides being a cool toy to have on your desk, it’s easy to see the educational potential of a 3D-printed replica like this. Students learning how to work on cars could get their hands on this, which is much easier to take apart and examine in a classroom setting than, say, an full-size Subaru engine.
Harrell says that he’d like to make a gearbox to go along with this engine, then create a replica of an LS1 V8 afterwards. While we’re on the subject of flat-fours though, I, on behalf of Road & Track would love to see a miniature version of the quad-cam flat-four used on the original Porsche 550 Spyder. That might be a bit challenging, but the result would be so, so cool.
