No, no, no. Don't work for free. Apprentices don't work for free in any other industry. Why should you work for free?
Go out and get a job that trains you to be "production ready." You will get to to work on bigger projects, "code, refactor", and do "grunt work". Plus you will get paid.
Nothing wrong with seeking an apprenticeship. I just don't understand why you would think that "free" is a good idea.
The title did get changed. I think the reason it was titled "after 3d printing" was because you can make a prototype with 3d printing, but what do you do when you want to go to production?
I think that the lawyers suing for class action status use one (or a few people) as their "examples" of people harmed by the complaint. Those people may make some money... You may just need to get into your class action suits much earlier...
