Indestructible Egg Holder

After looking at Carbon FIbre prices I realized that I'm Ferrari and can't afford it, so I'm going to go with my next closest option Fibreglass. It should be relatively strong enough and I can get my hands on it easily. But since FIbreglass isn't as strong as Carbon Fibre I'm going to have to add some more strength to my design so what I've decided is to make my container a ball. I'm hoping that if he hits it with the corner it'll roll away before he hits it. For the insides of the container I want to print them out of TPE. I'm thinking a sphere with gyroid infill that I can squeeze the egg inside is my best bet.

I currently have floating around my head. I have 2 FDM printers and a Resin Printer.  So for the inside I was thinking some sort of 3D Printed insert made out of TPE. The outside is where it gets hard. Now I think carbon fibre is my best bet but I don't know if I can get the amount I need with my budget, so pvc is another thought I had. Whatever it is it can't shatter.
