OnShape is my go-to. It’s what I taught my students when I was a TA for an introductory engineering class at college, and they could pick it up in about a day.

Can do just about anything a “professional” cad suite does, but it’s free, works in a browser, and is generally so much better designed so you don’t have to fight against the UI to get anything done.

Wait so what was the trick to save time and filament? Just rotating the part to use fewer supports?
