A point that I haven’t seen in the other comments is to make sure you fully own the Chromebook. If it’s on loan from your school, or if it’s provided by your work, then you may be bound by some acceptable use agreement and therefore not allowed to modify the OS.
I’m an engineer not a business person, but it sounds like the business itself isn’t worth anything. No sales means I have no reason to believe the IP is financially worth anything. Registering an LLC is pretty cheap. The hardware and filament could maybe be sold for a few grand, but it doesn’t sound like you have a massive print farm or much infrastructure. Sorry to be a downer.
I’ve heard that some people are interested in buying existing companies just so that they can have a company with some tax history. Maybe for slightly sketchy reasons. Almost like some people will buy old social media accounts.
If you are parting things up, I’d consider buying the Prusa XL and maybe a dozen or two kg of filament, but I probably wouldn’t go above half the price of a new printer, and the filament I buy is already cheap. You may be better off keeping the printer to just have fun with it.
