Not an answer to your question, but related. When I got into 3D printing, I started using FreeCAD. I found it horribly difficult to use. I switched to Fusion360, which is a joy to use, but it doesn't play nice. You can't collaborate with others, can't do commercial stuff, can't use more than 10 projects... I've since started on my own project. I'm a big believer in the idea that language is the most versatile way of working, so it's one of those editors where you describe the model in a programming language (TypeScript in my case). It's not ready for use yet though. It uses C++ on the backend in order to use GCAL (and its fast 3D boolean operations). The visual editor is in Electron, with Three.js for the 3D rendering.
