I designed a foldable popsocket that can be printed as "PrintInPace", so you can stick it on your phone case right after printing, always have it ready to use and it takes up almost no space.
I hope you will like it. Also don't forget to share your creation for others to see and maybe even remix it into... I don't know. For example, a phone stand :-)
