I use Fusion360 and it’s fine for my basic at-home needs.
They back-tracked on a couple of the restrictions added to the free version a couple of years ago (IIRC you initially couldn’t export step files, but they backtracked on that).
It’s easy enough to sign-up to & get a free version if using it for hobby means.
I find the way it works compared to Solidworks or Pro/E (Creo) a bit confusing when it comes to assemblies, but generally muddle through.
I am not sure about on a PC, but for your phone or tablet there is a simple model viewer available.
