Bagging suggestions for large tool

this nice tool was dropped off yesterday. It’s a side pod mold for a Carbir racecar. I will be making two ea,
I will bag the whole tool for infusion. My question is does anybody have ideas for the bag so it does not get stressed over the support fences. (sharp corners)

My first thought is to foam in the boxes for a more friendly surface on the backside.
I really don’t want to pleat the bag for all the details


thanks
