Ultra-Mega-Super-Duper Deck Box

Introducing the Ultra-Mega-Super-Duper Deck Box, guaranteed to fit 100+ of your double-sleeved cards. I use Dragon Shield sleeves. It's perfect for Magic The Gathering showdowns or any card-carrying occasion. 

Fear not the dreaded upside-down test; our deck box laughs in the face of gravity. Your cards will stay as cozy as a cat in a sunbeam, with no rattles or spills. Opening this treasure chest requires the finesse of a cat burglar—gently coax one side open, then reveal your deck's glory to the world.

Throw that manual out the window (not literally; please recycle)! There's no need for pesky support here. Just lay it flat like a pancake and watch your printer work magic. The printer is ready at a modest 0.2mm layer height for that "I can barely see the layers" smoothness. Behold, the deck box of the future is here, and it's spectacularly over-engineered for your entertainment. I print with a small brim to keep the corners from warping. Don't forget to post those makes!

I made the box slightly wider and longer and added the MTG logo to the top of the lid.
