Business/Credit Card Holder

A business or credit card holder with an integrated cover. The Y axis of the STL file is aligned with the build orientation I used; I could build it without any support structures (using Monoprice Maker Select Plus). The gap at the hinge is 0.3mm. The cover may need a little bit of force to break off the hinge to make it swing after building it. Note that in some 3D printers, 0.3mm gap may not be large enough and they get merged.
