Oldest newbee/disabled senior could use some help!

Hello! I’m a disabled senior stuck at home who decided to get a QIDI Tech Q1 PRO 3D printer. I wanted to do something to keep from going crazy (I’ve already binged watched every TV show, and surfed to the end of the internet) so I was hoping to learn something new, and who knows, maybe learn a way to make a few extra bucks to help out at home.

Anyway, I used all my Amazon gift cards (given to me over the years) and got the 3D printer. Unfortunately for me, before the printer arrived, I went into the hospital and almost died from septic shock. After a few weeks in the hospital, and then some more in a rehab, I finally got home. There was the printer, still in it’s box (my kids brought it inside). Heck, I don’t even know if the thing works, and it’s past the 30 day window to send it back to Amazon if it doesn’t. In any event, I’m still using a walker and wheelchair so lifting the thing out of the box hasn’t happened, although I’m going to ask our kids to take the printer out of the box (when they come up to visit for Christmas).

My question for the folks on this forum is what to do next? I had watched tons of videos about 3d printing before ever deciding on getting one. I though I had a good idea of what to do. Now, as a result of my ‘adventure’ with the septic shock, I have no real memory of the last 6 months or so, much less what I learned about 3d printing. Everything I thought I knew, and all my plans having to do with 3d printing seem to have vanished. I didn’t even know what kind of slicer or extruder my printer has/uses.

Hoping folks here can help me catch up. I’m not even sure how to take an idea from the design stage to the finished 3D print. I know there must be some computer programs that help design something (don’t know which is easy to learn or use), and there must be a way to get the design into the 3d printer to be printed - but I’m drawing a blank. Hoping I can come here with all my dumb questions for answers. So, any and all help, advice, suggestions, (and even ‘hand-holding’) would be greatly appreciated!
