No hardware or glue required! A simple, fast-printing adjustable phone and tablet stand that can achieve continuous angle adjustment from vertical to nearly flat. The optimized center of gravity makes it comfortable to accommodate phones and tablets in portrait and landscape mode (at a nearly horizontal angle, tablets may have difficulty in portrait mode). It consists of only three parts that slide/snap together easily.

Assembly instructions: 
Slide the mobile phone holder into the base

2) Slide the knob shaft into the cutout of the base and snap it into place
