One of the fun holiday rituals growing up was when the holiday greeting cards started arriving at my parents’ house — especially the group photos of people donning Santa hats or their ugliest Christmas sweaters. My mom tended to keep in touch with everyone she had ever met, so we received a very large batch of cards in the mail each year between December and New Year’s Day. She’d try several ways to display them over the years, sometimes taping them up to a door or placing them on the table. But they would inevitably be moved by one of the kids, which would upset her, so she’d always end up just putting them into a big basket that we would pass around. 
It wasn’t the most practical way to organize the greeting cards. She could have really used something like a Greeting Card Stacker, which is 3D printed and featured on Thingiverse just in time for you to prepare for the holidays.
New Zealand-based Murray Clark, who designs as “Muzz64,” the Card Stacker designer, has devised a very simple system including different ways to stack your cards: offset or straight, on a table or even the floor for a very large tower of cards. Each Card Stacker is designed to work with almost any kind of card, is very lightweight with thin walls, and uses very little filament. Printed with a 0.20mm standard resolution with a 75% infill for strength, the Stackers have little grooves to place the cards. You can increase the scale a little if the grooves don’t come out clearly during your first print.
These Stackers do come with a few tips for use from the designer. The first is to always build your stack off of a base Card Stacker which functions as a solid platform for the rest of the stack. 
The second tip is to adjust your Card Stackers so they stay straight; the stack can easily topple over if not put together right. According to Muzz64, if the stack is arranged right you can have up to 6 cards in a stack. It’s that easy.
So after you’ve printed your Stackers and arranged them for the perfect display, you can kick back and enjoy your holiday greeting card collection in a new format besides next to each other on a tabletop taking up space, or in a big pile that inevitably develops because you no longer know where to put them all. Muzz64 has solved that annoying problem for you with this inventive Greeting Card Stacker that looks easy to 3D print and assemble too!
