Bicycle - cellphone stand

This is my first print I have designed and would like to share. It is a galaxy s7 mount for my bicycle, Includes tie wrap holes but if you print at 100% infill it has a tighter grip than you will ever need. Consists of two parts that one slides in the other and secures with a screw-threaded instet if you like. Lower part can be printed with lower infil as low as 0%. Will work but has weaker grip on bicycle.

Feedback or questions is more than welcome!
