I hate these foam cases especially the square pre cut ones, 1. because once used you can't put the bits back to re arrange for a different layout and 2. they fall apart.
ME I prefer to make my own dividers, this is an OLD layout now much changed but the dividers made of . see link.... can be moved again and again in a case
Also plenty of room for air flow and no chemicals like foam
