extra leg for foldable phone stand

This is an extra leg add-on to the foldable phone stand made by @Michal1980. Awesome phone stand, but it has a tendency to fall backward when my phone is in portrait mode. I made an extra leg that clips onto the back to give it more stability.@Michal1980's foldable phone stand https://makerworld.com/en/models/623240-foldable-phone-stand-automatic-arms#profileId-547425
