I’m using Fusion360, and I dislike it for a lot of reasons, but it’s easy to use. I tried FreeCAD, but it was very janky in comparison. Shapr3D was surprisingly good, but there’s no way I’m paying monthly for my hobby usage. I need precision prints, so I can’t just use Blender or similar.
Is there some magical unicorn software I’m not finding?
What sort of precision are you not getting from blender?
Once you set the parameters (I set mine to mm), I have found it to be accurate enough to make additional tools with which to measure.
Mind you, I don’t need accuracy down past a mm.
