I've created the model below for 3D printing, but when printed at my desired size, each piece is too thin and flimsy. I was expecting it to be larger when I modeled it. Is there any quick and easy way to "bulk up" all parts of the model at once without scaling it? This is hard to explain, but hopefully it's making sense. I'd like the overall width of the piece to remain the same, (or very close to it) while each of the long, thin sections gets thicker. It would be a major pain to do by manually moving or scaling individual sections, and it seemed to me like the kind of thing that there might be a modifier or sculpt tool for. (I'm not very experienced, in case that isn't clear, so I think there's a good chance I just don't know about a tool that would be perfect for this)

(If someone understands what I'm getting at and can offer a better way to explain it, I'll happily update my question)

3D model with thin pieces


Well, it turns out I should have kept trying for another half hour before posting.

For anyone else with this problem, select all in edit mode, hit Alt+S to scale along normals, and then, while scaling, hold Alt or S to use something called Even Thickness to keep it from "bubbling" out.

I'll wait a while to mark this as my answer, in case someone else has another option that works better

    $\begingroup$ You can also use "Displace Modifier" to achieve similar effect, and it could also use a custom normal, and vertex weight as well. $\endgroup$ – HikariTW Aug 4 '20 at 1:51

    $\begingroup$ For single-sided meshes the "Thickness Modifier" works too. $\endgroup$ – KYL3R Aug 4 '20 at 12:39
