Card holder (for kitchen noticeboards)

I never found a good place to keep loyalty-cards. There are just too many of them to keep them all in your wallet and we share the cards with the family. Therefore the kitchen noticeboards seems a logic place to keep those cards handy. The design is ultra-simple but very rewarding ones you superglue it to your noticeboard. I strongly suggest you do the same ;-)

Just print as many as you have cards and superglue them right on top of each other. Use slic3r to print more of them at the same time
