OpenScad was a random choice, pure and simple. People seem to use one of 3 products. OpenSCAD, Fusion 360, or Blender. Since the free version of Fusion 360 says is has a reduced feature set, I tossed it out of the mix. That left Blender and OpenSCAD, I picked OpenSCAD. It was a coin flip choice.
OpenSCAD was a choice based on a random throw of the dice.
After owning a printer for about a month, I had to pick something or relegate myself to printing other peoples doo-dads which was a non-starter for me.
