If you're doing enclosures, check out Dune3d! Has been featured here as well (it's how I found it). It's pretty easy to use and feels intuitive for prints you'll only have to make once or twice. It's missing some things here or there but nothing fundamental (except trimming edges i.m.o.)

I often switch between FreeCad and Dune3d now, Freecad for things I know how to design properly and Dune when I'm in 'claying' mode. E.g. export a .step part when I get stuck in FreeCad, import it into Dune, make some progress and vice versa so I don't walk away from the project
