If you’re a guy, chances are you’ve probably opened the hood of your car, poked around for a bit and then thought “Yep, that’s an engine”. While most men are fascinated by engines, unfortunately many of us can do little more than check the oil. But if you’re eager to learn more, you can now do so at home without taking your own car apart. Mechanical engineer Eric Harrell has just shared a 3D printable 35-percent scale model of a Subaru’s EJ20 flat-four engine that is fully functional, though obviously not a real engine. A perfect 3D printing project that will teach you all about how engines actually function.
If this project sounds familiar, that’s because this isn’t actually Harrell’s first 3D printed engine. The mechanical engineer, who goes by ERICTHEPOOLBOY online, has previously shared numerous fantastic car-related 3D printing projects, including this working 3D printed replica of a Toyota 4 Cylinder Engine 22RE back in January. Most importantly, like that Toyota replica, this Subaru engine is not an actual engine. “It’s fully functional as in all parts move as intended in the real thing. Do not confuse it with a real engine, as this is not,” Harrell says.
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
