Maker Eric Harrell has made a working 3D printed model of a Chevrolet Camaro V8 LS3 engine. The car lover used a combination of 3D files from the internet and his own models based on images, repair manuals, and diagrams.

First introduced in September 1966, the Chevrolet Camaro has fashioned a reputation for itself as a stylish, reliable pony car, and a worthy rival to the Ford Mustang. Apart from a brief pause in production during the mid-2000s, the Camaro has remained on the road since the 60s, even featuring (in a somewhat different form) as the fictional robotic character Bumblebee in the Transformers movies. So whether you’re a Chevvy lover or an Autobot, you’re sure to love this incredible 3D printed Camaro V8 LS3 engine, made by maker Eric Harrell using a mix of original and found CAD models.

According to Harrell, who uploaded a video of the working 3D printed engine on YouTube around a month ago, the LS3 model was entirely 3D printed, except for the bearings and fasteners. Some of the 3D models for parts were found “floating around the internet,” while others were carefully sculpted by Harrell himself using images, repair manuals, and diagrams as references. Harrell has actually produced a number of similar engine replicas, some of which were copied first-hand from the real thing. The maker has, however, admitted that he “did not have the actual engine for this one.”

If 3D printed engine models are your thing, we have further good news for you, because Harrell has uploaded all 3D printable files to Thingiverse and put together a number of kits for the other parts: “Hardware kits are available for $52 for all the fasteners, bearings, rods, springs, and the belt,” he says. “Fasteners and rods will have to be cut to length as indicated in the parts list. I also have the 500rpm motors for $17, speed controller for $6, 12v power supply for $4. Everything should all fit in a flat rate envelope, so $6.95 for shipping in the US.”

Harrell recommends printing the 3D printed parts of the Chevvy Camaro V8 LS3 engine at .2 mm resolution, with an infill of 20 percent. For his own model, Harrell used around 2 kg of PLA filament, which printed over the course of around 200 hours. The maker is also selling fully 3D printed and assembled engines.
