This is a card holder that fits Catan (or other game) cards. The excellent original called to glue or bolt three of them side by side and you've got yourself six slots.

Glue, bolts? What are we, barbarians? I also wanted to use them NOW, so the idea to use the Parametric Snap Pins in place of glue or bots came to mind. 3E8 was kind enough to provide an "unholey" version, and I added the parametrics. Enjoy!
You will need 3 "card holders" and 2 "snap pins" for a "complete" unit.
