I don't think people understand how much value we get from NASA... Like, $7 for every dollar spent, or more, in economic benefit and technological advancements. So many solutions they have to come up with to make space flight possible are incredibly useful here on Earth too
Value that we won't get if we're paying a private company to do it
An octopi is a fun project, for mine I printed a new internal enclosure for the mainboard that has mounts for the pi, so the printer is completely integrated with it (never did finish setting up the internal power routing to power it directly off the power supply, but that's also completely doable)
