"There's not a single language I'd consider myself good with"
If possible try to focus on a single language. Build a lot of different little things to cover the breadth of the language. Find a job where you only need to contribute in that language. When you become proficient at that language (this can take years!), then you can pick up other languages much easier, and you should feel more confident in your knowledge.
Around that time (or maybe slightly before) I was asked by my friends dad to figure this out. He and a group of his friends payed for the equipment and gave it to me. I figured it out, but when they found out that the "hack" would be reset at least every month and before any major event they all found it too problematic to deal with. Worked out great for me as I got free satellite TV for a while when I was going to school.
As others have said you export an STL file from your design software. This goes into a slicer (Slic3r, Cura, etc.) If you set up your printer with OctoPrint running on a Rasberry Pi you could do the slicing there, but you quickly run into the limitations of auto-slicing.

Others are either gaming related that I don't watch much anymore (use twitch for that) or things that have been mentioned several times already.
I blocked the webcam, then tried again and it gave me the option to upload photos of my ID instead. Not sure why that wasn't an option in the first place like it is on coinbase.
I had this situation. I had an AWS account linked to some email I no longer had access to and could not get into the account. I opened a support ticket and they sent an email to the old address, after 10 days of no response they sent it to "Legal" for review. The account was then closed by them which resolved it for me.
