PIMA key fob V1.4

We had situations where key fob locks office security when it is placed in bag, backpack or even in pocket, so i had to make sure it never happens again, with this model it is possible to prevent this fustration, and it is easy to print. It is pretty hard to get exact measurements, but it is close enough to work properly. In future versions i will reinforce outer walls of keyfobs upper portion and remake buttons enclosure, but for now on it is working as it should, no interferience and no downgrade from existing PIMA key fob.
