I actually have been working on my VF-1D slowly but slowly. I got stuck on step 1. Even though I've made quite a few of these over the years I guess I've forgotten how badly some of the pieces fit together, and this is especially obvious on step 1 with the exhaust nozzles/feet. Not only do they not really fit together, but there are no guide pins, either. It's kind of the wild west with them. So I got to this point and got frustrated:
You can also see places where there are ejector pin marks that are really hard to get to as well.
Then I remembered I have a couple 3D printers. So I gave up on those pieces and decided to 3D model them and print them out. After some trial and error here's what I finally replaced them with:
At least I'm on step 2 now.
