Yes, tapered in all directions at once. For instance one of the walkies has a rectangular base and an almost straight-up backside, but the front tapers outward. At the same time, the sides taper too, but different angle and height than the front. There are almost no right angles on these shapes anywhere, which is tedious to model.
I’ve looked at OpenSCAD but it’s honestly too much coding for me. TinkerCad is so rewarding because it’s fast and easy to get nearly to the finish line – but I know that any kind of parametric is a win in the long run, because changing one constraint makes everything else auto-adjust rather than having to take apart and build again.
