Card Holder/Insert for Exploding Kittens

cults3d

UPDATE: Added a version for sleeved cards that requires two trays to hold all sleeved cards from the base edition. I didn't like any of the inserts/card trays available for Exploding Kittens, except one - https://www.thingiverse.com/thing:1957634. This design itself is a remix of another popular model, https://www.thingiverse.com/thing:854289. However, it's too small and the tray can move around in the box. So I started with https://www.thingiverse.com/thing:1957634 and first widened it a bit to make two trays that fill the box in its width. Unfortunately, they still move around along the other dimension. Next, I experimented with adding a "hump" to the back of the trays to anchor them in place but ultimately decided on a small lip in the front instead, which looks nicer and uses less filament.
