Hipster cardcase with lock
This cardcase can be completed without glueing. Just print it and cut it. Scorch the folds. While cutting, don't forget the small horizontal cut int the most left section, and the two tiny cuts on both sides of the lip. This way the lip will function like a barb on a fishinghook, when you fold the cardcase and put the lip in the cut.
Just print, cut and fold...
