What types of questions should I avoid asking?

You should only ask practical, answerable questions based on actual problems that you face.

Your questions should be reasonably scoped. If you can imagine an entire book that answers your question, you’re asking too much.

Have you thoroughly searched for an answer before asking your question? Sharing your research helps everyone. Tell us what you found and why it didn’t meet your needs. This demonstrates that you’ve taken the time to try to help yourself, it saves us from reiterating obvious answers, and above all, it helps you get a more specific and relevant answer!

My observations:

• Your question is not based on an actual problem that you face.

• It is also too broad, it includes 14 separate questions.

• You have not demonstrated any research in your question. A search for "how are keycaps made" produces dozens of articles on the topic of your question. There is a Wikipedia article which covers the basics and other articles which go into a lot more detail.

I would therefore have closed it as off-topic as well.
