I just saw this post and wanted to add my two cents. I definitely will incorporate 3D printing into my build for some parts using something like nylon or another engineering filament. Right off the top of my head I need to break out Fusion and design some hard line mounts that'll go on the 4" main rails, plus a nice mount for my Holley inline fuel filter. I know as I move through my build I'll come up with other needs. I'm mostly focusing on functional pieces where I can't either find what I need or have a unique set of requirements. But the net-net is that with a custom build such as ours, there are lots of opportunities to incorporate 3D printed components. And for structural and/or decorative items, there luckily are job shops online for metal printing (as M22_COBRA is doing). It's a great time to be able to do manufacturing like this in our own basements
