Even for newer equipment that may have been imported and for which parts are hard to find domestically. Right now, I have a Yanmar F15D with a broken front grille. It's made of molded plastic, but it's one of the parts that I would probably have to special order from Japan. Don't know how far off is the ability to print parts with the integrity of hardened steel. ?....
You don't need to! There are several libraries filled with tens to hundreds of thousands of designs, ranging from marble tracks to spare parts of old appliances. Even something as a custom gear can be generated quite easily, fill in the diameter, amount of teeth, pitch and this site will generate a design for you.

The only reason I haven't got into 3D printing is that I haven't wanted to put in all the time to learn 3D modeling software. I figure if I ever NEED a 3D print I'll just have to pay someone to make it for me. If you are going to go for it Tom, then the turbine blade math and fluid dynamics probably aren't any harder than the rest of the modeling process.

I'm happy that after the border with Venezuela closed a few years ago there was at least some realisation that there needed to be more local production so some old market gardens got a boost. At least the shelf stable and frozen staples can still come in via container ships, so even though the menu will be limited nobody should get hungry.

Have you used these? Got any brands/names to share?
I searched and found references to the idea, but no actual products. There are plastic alternatives for vacuum sealing, but the ones I found all indicated they weren't suitable for sous-vide cooking. : (
