Dude, coat hanger joint is broken. The free chatgpt gives openscat file I can just paste and convert to stl. I didn't even measure the diameter of the pipe, apparently those are standard. In 10 minutes I have a new 3d printed part to fix my coat hanger. No CAD UI app subscriptions, not reading CAD books or whatever. That's real life. Rest is in your mind.

You surely don't think you can scale from that to more complex parts.
