phone suport adjustable

Just wanted a phone stand I could use for reading AND charging but couldn't find one single design I liked that was super stable and didn't allow my phone to wobble..

both the ball n socket and the phone base were remixes from other stuff.. I'm looking for the originals to add credit but can't find them as yet, will add the links as soon as I track them down

ok ball and socket from here https://www.thingiverse.com/thing:1085548 had to split them into male female parts as I only wanted one half, then I cut the ball off the male side and grafted it onto the screw thread part

here's the phone holder https://www.thingiverse.com/thing:652214 had several issues.. still wasn't wide enough to be really stable, the head part of the screw support the little tag bits printed as almost separate parts and fell straight off and it just didn't fit properly against the back of my phone.. .. if , as I did , you use a little thin grippy foam rubber on the disk that touches phone its even bett
