Card Holder

Minimalist Card Holder and Stand – useful for Notes, Cards, and Displays
This small card holder is perfect for organizing and displaying flashcards, playing cards, business cards, mini signs, or even more creative things like targets for Nerf Blasters. Its design keeps cards upright and visible by allowing enough flex to clamp down on cards, without taking up much space, meaning that it does not cover anything being displayed. 

Does not need supports, works great with PLA, but PETG will allow for more flex if the card is bulky. Can be scaled down to fit smaller things aswell.
