This is a great intro to the code-based 3D modeling CAD software called OpenSCAD. If you are a coder or just good at math, you can 3D model like a pro with an easy and intuitive interface that requires virtually no learning of complex UX paradigms. Best of all it is free and open source!
This video walks through creating a 3D model for an adapter to support a patio umbrella inside an aluminum square tube leg on a boat dock. I printed this part using PETG filament on my Creality CR10s 3D printer.
