<p>Context: I have absolutely no knowledge of 3D printing other than you need a computer, a printer, some software, and a design. That is literally the extent of my knowledge on 3D printing.</p>

<p>However, I have an idea of something I'd like to have 3D printed. While the idea has a fairly reasonably defined shape in mind, it doesn't exist in any digital or paper format and has some specifics that still need to be filled out (such as accurate dimensions and a few design details).</p>

<p>I need to bridge the chasm of knowledge between my current design and limited knowledge to a fleshed-out design file with chosen materials and other specifics. A good chunk of my problem is that I don't even know <em>what</em> I should know. While I realize that this site is still fairly new and things are being nailed down, how do I ask the proper question(s) to fill in my knowledge gaps that will be on-topic for the site? Is there even a path forward for these kinds of questions on the site?</p>

There is a
new question on Meta
that should help define what is okay on this site.
However, your question is important to address here.
Ultimately, you shouldn't be afraid to go ahead and ask the question. If the question does not meet the conditions of the present site, the general public will be sure to let you know and (hopefully) help direct you in at least asking a more direct question.
If you post a question that is closed, it would acceptable to post a question here on Meta that specifically asks how to make your question fit within the scope of the site.
I would suggest providing as much information as you have and feel free to ask the more general questions about 3D printing. Most people in the community will ask specific questions to try and help you. Some may even be able to fill in the blanks of what you're asking and provide you with very helpful answers.
