Riftforce insert (is bad)

I wanted to make an insert into the Riftfoce box (217x217x39).

But there are a few negative points, which is why I did not use it:
1. It does not work well with cards in protection. They fit tightly into the slot.
2. There were only 14 slots. Which is not very effective and is not suitable for playing with an add-on.
3. You need to remake the walls - reduce and make a notch for the finger.

I'm posting this to share my experience. Perhaps this will save someone from mistakes and give hints for their projects.
