Are there any other automotive enthusiast/electronic hobbyists out there with a 3d printer? Check this out:


I am going to make a run of these I think. Maybe 3-5 of them to pass out to those that are the most special to me in my career. If any other printer owners out there might be interested, the files can all be downloaded from thingiverse right here: https://www.thingiverse.com/thing:1911808

It looks legit and works and will make a nice display piece on anyone's desk. There are even some longtubes and a flywheel I can print to complete the assembly.

The really awesome part about this is that is bolts together like the real thing. No glue. And so once I have it together I can change printer nozzles to smaller diameters for finer resolution and get different type and color filaments and I can chase upgrades and improvements and swap parts at will and just see how sweet I can make these things over time.

Wow this block takes days to print. It was gonna take 2 days and 18 hours to print out but I changed the layer height from .2mm to .3mm and it shaved a whole day off the print tine. I am currently 16hrs into printing and 34% complete..



...then we will work on the head castings.

Well that took forever. Or 40 hours, 18 minutes, and 40 seconds of non stop printing to print out the LS3 engine block. At least it came out nice..



Next I need to work on the cylinder heads before printing out the internals.

How big is it? Looks great. I love your new "Toy". :laughing:
I think it is somewhere around 1/5 scale. Everything looks just like the real part. I have also printed out the main caps..



And rear, valley, and timing covers..

I am waiting on hardware before I can really work on the internals and now I am waiting on more silk silver PLA before I can start printing the head castings so I am jumping around to see what some of the other external pieces are gonna look like. I printed this LH exhaust header on my home made printer, Printalicious..



Because my Black Widow printer is spending the next 20 hours printing out the intake manifold..

That's looking great. I'm afraid Id have to complain to GM Customer Service about the excess casting marks on the intake. The resolution doesn't look so good in the pic.

The parts I ordered from https://www.makerrx.com/ have shown up. Here is how the LS3 hardware kit comes packaged..





And here are the timing 'chain' the valve springs, and the rod, main, and camshaft bearings..



Now i can start working on the crank and the cam. But first, I need a stand to bolt the block to. Here is how the engine stand arrived..



So i have my work cut out for me before i can even get this motor on a stand. Looks like i might need the dremel.
