Adjustable Phone Stand (Fully Printable, No Supports) 3D Print Model

Summary
I designed this to be an adjustable smartphone stand that you can very finely adjust the viewing angle of your phone or small tablet.
To assemble:
Slide the screw all the way in to the stand.
Turn the screw until it is fully seated against the frame.
Install the snap ring over the smooth part of the screw, against the frame as depicted in the photos.
Note: This design can be scaled up to suit large tablets if you so choose.
