OpenSCAD does the job for me, though I’m not particularly experienced in CAD things. I’ve tried FreeCAD and Fusion 360 (on Mac) previously and they just look too confusing for my taste.

With OpenSCAD I can at least approach the modelling in the same way I approach things at my say job: just write some code 👩‍💻
