Card Against Humanity Card Box - With sliding laser cut wood or 3d printed lid.
This box was designed to hold a large amount of cards! no exact count yet but you get the idea ;)
The 3D printed lid slot overhang has proper angles to avoid the need for support material :) enjoy.
Update: There is now a 3D Printable LID! Thanks to mother-of-crafts-3d:
