This is the card clamp, a clamp which lets you hold your card while you play, or quickly changes to a display that can display your cards to the world, from sports to Pokémon. This clamp should be able to be printed in most filament, mine using PLA.

This clamp is fully printable, but it's up to you to choose the cards. the clamp clamps on surfaces ½ an inch, to 3 inches, and has a slot for the 2 card holders that can easily switch between each other. The playing card holder holds most average playing cards, like Cards Against Humanity, Uno, or a standard deck of cards. The trading card display holds most average sized trading cards equal to the size of a Pokémon or Baseball card.

This print is best separated into two prints. Group 1 is “Clamp” and “Screw” >24% infill, no supports. Print the bolt head down, and the Clamp in the shape of a laying down C. These parts are required as they make up the clamp itself. Group 2 is the "CardDisplay" and "CardHolder" >10% infill, supports everywhere. Print both of the card holders upright, and the supports are relatively easy to get off. These parts aren't mandatory. “CardDisplay” is the frame for cards, while "CardHolder" is the adapter to put cards in while playing games. Goodluck printing!

UPDATE LOG:

(6/26/23) added the files for a customizable slot, so you can add anything you want, and the STL files for all of them, to be more compatible with printers.
