Thanks. I still have a lot to learn about 3d printing and have many more tweaks to do but, the nice thing about 3d printing is you can reprint the part as many times as you need to get it right.

The radiator looks very good! I'm anxiously following this thread.

That's what I like about 3d printed parts if drivetrain components wear out you can just print new parts. I love metal models but this 3d printer is allowing me to model at much greater detail and scale then my current metal working tool would allow me. The 3d model for the radiator took me 2 weeks to model. But it's the centerpiece of the front of the model so I wanted to get as scale and detailed as possible.


Anyway, while I'm waiting for the aluminum for the frame to arrive I have started modeling the cab. It's made of mostly styrene but the roof is 3d printed out of PLA. It kind of looks like the cab on a Peterbilt 334

Quick update. The frame is starting to come together, I still need to design and print the brackets for the cab support rails it also needs the dump bed rails.






The driving driving gear and tracks are coming together nicely as well. it will work just like the real machine with a sliding frame and springs to keep track tension, A rocker block, runner blocks and a chain of track rollers for that "Flexible Traction" system that made LINNs different from other half tracks.
