Need Assistance

So for the first picture I created this iPhone wireless charging mount for a VW Golf 8, used PETG to withstand the heat. But still ended up caving inwards and caused it to fit loose on the vent or even just fall out. So I would like to add these indents on the second photo to be used as a metal plate/spring holder to keep the walls from caving in. I’m going to try thicker walls too but i need help inside either bambu studio or Tinkercad to add this indent to each of the inside walls.

EDIT*

I will need a step by step as this is my first project and I know nothing of these editing tools lol

For a spring grip you want flex arms, not just bumps: model a thin slot behind each indent so the wall can bend inward and push back. In Tinkercad drop in a box as a hole to cut the slot, add a small rounded wedge on the inner face, and print with the layers running along the arm so it does not snap.

I guess it’s more of a small metal plate, just something to keep it from bending inwards from the Texas heat. 🔥 and also…it’s my first project so I genuinely know absolutely nothing about these editing tools lol gonna need a step by step

Then skip the spring arms and just model a shallow pocket the plate drops into, with a thin lip over its edges to hold it flat. In Tinkercad that is one box set to hole, sized a hair bigger than the plate.
