Some things I have been working on

Very nice modeling.  It's good to have you back. 
I get tempted to try 3D printing but I have more irons in the fire than I can handle now and the learning curve is above my level. It does look like t could be fun though.  I think that Shell station is a nifty idea. You should send Shell a photo. Maybe they will give you a tank of gas

I seriously would not suggest adding more irons to the fire.  I only started doing it because I could "build" models on my computer while I was with the kids when I did not have time or space to go out to my workshop or get out modeling supplies.  It's fun and challenging, but I get more satisfaction using time-honored techniques.
