Tinkercad is worth a look. Web based, owned by Autodesk, and it's free to use.Yeah I still need to figure out a decent CAD program that will work in Linux before I get into 3D printing, and I'm not a fan of cloud based stuff, I won't touch Fusion just out of principle. FreeCAD is about the only thing in Linux and it's a huge pain to use, it's like someone had a contest to design the worse UX and won and they used that.
