Not sure what size you'd need but I've been drooling over this one lately:

It's a combination 3d printer and a vertical milling machine.

dramatically increased their production rate, and my math is out of
date. If so, it has done surprisingly little to the price of prints.
How many chambers does Ursa make at a time or per year? Rocketlab hit
their 100th engine less than six months ago, and they're one of the
larger consumers of printed chambers.

With high value payloads perhaps. That seems like an expensive
opinion but perhaps focusing on designing and producing an inexpensive,
simple and reliable booster in vehicles this size and forgoing recovery
would make more sense from an operational cost standpoint. Or perhaps not.
A few successful missions should confirm it either way.

Someone I have known for a long time asked me about using a remotely
controlled helicopter to aid recovering the SpaceX fairings.
It is a topic about which I don't know enough even to be dangerous.
But I said I would try to find someone who knew enough to critique his
ideas.
If there is such a person on this list, and you are interested, I can
pass on this guy's email.
