Redmi Note 5 Gopro base mount

I have one of those Gopro "flexible gripper arm" things. I made this to be able to use it as a phone holder, primarily so I can use it as a biking satnav. Will work with any gopro "shoe", such as the small stick-on ones too.

Designed for a redmi note 5 with TPU case, may fit similar-sized phones too.
