It only replaces the big tray, it holds all the sleeved cards needed for the campaign mode, + the mission box tray can hold the upgraded character cards from the Personal Stories box.
I keep all my Zone Survival cards in the SG box.
I put the anomaly layouts in the token tray, since that needs a new place.
It's not perfect, nor it is fancy but it gets the job done.
Printed in PETG 230/80, but should print just fine with PLA with normal settings
No support needed
I would advise using a brim/raft if you have sticking issues.
