You are right, this insert is for the old, smaller, box.
The new box already has an insert with slots not unlike the ones in my design and enough space for all the content.
I prefer the compact design of the original box, but if the originally planned number of 10 expansions is released (fingers crossed), I will have to switch to the bigger box as well and will likely create another insert for that one too.
