Card Holder/Insert for Exploding Kittens

thingiverse

UPDATE: Added a version for sleeved cards requiring two trays to hold all base edition cards. I disliked every insert/card tray available for Exploding Kittens except one - https://www.thingiverse.com/thing:1957634. It's actually a remix of https://www.thingiverse.com/thing:854289, but the design is too small and the tray can shift within the box. Initially, I enlarged it slightly, allowing two trays to fit snugly along the box's width. However, they still wobble in the other direction. To address this issue, I experimented with adding a "hump" at the back of each tray for better stability but ultimately opted for a small lip on the front instead, which I believe looks more appealing and saves filament.
