I've been a newbie too and tried to use FreeCAD as others mentioned but I found myself enjoying build123d (basically a python library that uses an long-existing technology called OpenCascade and a viewer called OCPViewer generally used within visual studio code). The learning curve is still there, but I felt more empowered to adjust/share 3d printing designs made in it over dealing with quirks of GUI-based CAD applications. The discord community on there is rather helpful too. https://build123d.readthedocs.io/ https://build123d.readthedocs.io/ https://github.com/bernhard-42/vscode-ocp-cad-viewer https://github.com/bernhard-42/vscode-ocp-cad-viewer I'll still use FreeCAD on occasion as a secondary viewer for stl files, though my hope is to use build123d entirely including for describing joints as well.
