Marvel Remix remixed - simple insert with card holder

Hi guys, 

this is a simple insert for the game Marvel: Remix.

https://boardgamegeek.com/boardgame/359152/marvel-remix

The insert consists of 2 card trays (one for Remix and one for Villian cards) and one card holder. The card holder is used as a filler in the box but can also hold the cards in the common discard pile during the game. Suggestions for better stability are welcome.

I initially printed 2 trays which are looser in the box but firmer for the cards and vice versa. Providing both versions.

Tested with 80 micron sleeves.

If anyone wishes to improve this design or suggest improvements etc., it is highly welcome.

As this game is called Remix (ba dum tss) this insert is remixed and inspired by :
