Human Punishment SD 2.0 + Hellgate Insert

I hope you liked my interpretation of a good insert for Human Punishment.

I wanted an inlay...
... that can be used to store my cards separately.
... can be used as a draw and discard pile holder.
... for standard-sized sleeves.
... without corners.
... without filament waste.

Inspiration comes from Deifel.
I liked his solution but it does not fit my requirements.

PS:
I am not sure about the cardboard.
I don't have them so I can't calculate if they fit on top.
