Here is a Remix of Jooxoe3i's print in place Easter Egg found here (https://www.thingiverse.com/thing:743276/). I just added a small cut out for your fingernail. If you have issues getting the hinge or tab to start, or fit, trying reducing your flow a bit (maybe 95 percent?) it always help for fits :D
