I would separate claw and arm into different files

these grip_width*4.5s, I'd make them named vars

intsead of for() rotate(i*...) translate(i*...) shape(), you can do mirrored([x]) shape()

I'm pretty sure this cantilever is much too small to print.
Also, is it an issue that these cantilevers become inseperable, as opposed to, say, screws?

Done! And if they're effective we can add a 'retraction' angle param that allows them to be extracted (just with more force with a stiffer angle).

can the arm and claw be different colors? :D

And include_gears on claw() can be removed, right?

for the todo, if it needs to be shared then either make arm.grip_width part of constants.scad, or in arm.scad add:
module offset_by_claw() {
translate([cube_size/2 + grip_width, 0, 0]) children();
}
and here you'll be able to just do
offset_by_claw() arm();
claw();

Done! Just went for the constants approach here.

Two things: one, you can probably use mirrored([y]) here, though it'd still have to have a translate since the cantilever is aligned on y and these points aren't.
Two, you might want to make this a module, like "module curved_armpit" :) seems like it could be useful elsewhere!

Done! Holding off on module extraction until we need to reuse it.
…egative cantilevers.
Resolves #4, still needs to be printed/validated.
