Tell me ideas on how and what to make holders (packaging) for the tool.

Thought to make a cool box for tools, that would go to an elite installation :) (joke). In general, there is an impromptu case in it you can and need to put the tool, the idea is to make it as simple and convenient as possible so that you can take it out and put it in a different order, as well as to fix it all and not hang out.

I will dilute the question with photographs - it will be clearer.

I already experimented with the case, it turned out to be flimsy, but that's not the point. To reinforce for a short time the issue in the system of positioning, fastening and the possibility of removal. You also need to think about convenient packaging for pliers, screwdrivers and drills.
