Comment on How do you build complex shapes?

“Wedge shaped”? as in at an angle, or tapered?
If you want tapered then openSCAD has scaled extrusion or hulls. I think Fusion has similar tools.
The way I do this in TinkerCad is that I build the hollow first
Open SCAD calls that “difference”.
If you’re working in fusion you usually want to start with a 2d sketch and extrude it. You would make each holder as a component and then attach them later.

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.

That is because the holders go around an injection molded part and you need to add draft to injection molded parts to ensure they can eject out of the mold. Every CAD software worth using will have the feature. You just model the part with straight sides and then add the drafts in a letter step (before you add rounds/fillets). The features generally work by picking some references to define where the draft starts from, which direction to pull the surface, and the surfaces or edges you want to draft.
Honestly, the parts you show are super basic. If you sat down for an hour and read documentation on the basics in Fusion360 you would be able to replicate parts of that complexity no problem.
