I wanted some hard cover boxes to keep my Star Wars Sabacc and Pazaak cards in so that they wouldn't get ruined. I know there are probably hundreds to choose from on Thingiverse, but I am also new to designing and wanted to give it a try and i figured a rectangle would be an easy start. In any case, here it is. I wanted to have them slightly loose, so if you want a tighter fit, adjust the lid size by a millimeter or two.
