For software I use Inventor, work Solidworks. I also use F360 and its pretty good. People make some amazing things with F360. It also has CAM for machining.
Printers: I'm one of the knuckle-draggers with a Prusa I3 for FDM printingi. I bought the kit. It took me a while to get it together, but it works well right out of the box. Although the Prusa technology is now dated I like their service and support and what they've done for the Industry. Would like one of those new Bamboolabs. I like Prusa-slicer software for slicing, its worked well for my parts.
I also hear good things about Flashforge Finder printers - don't own one but follow folks who make amazing models with em.
I also print resin - which for detail stuff cannot be beat - Elegoo Mars and Saturn. Nice machines for the money.

As others have said 3D modelling and printing bring a lot of new possibilities to the table for the tank hobbyist.
