Universal Phone Mount - Peg Attachment Remix

This adds Universal Peg Attachment to this amazing toolless phone mount.

I'm using this combined with the Universal Peg Ball Joint: https://www.thingiverse.com/thing:6737176

and the Ender S1 Pro Universal Peg Attachment Base:

This allows me to have a perfect camera angle for Octo4A.

USE SUPPORTS FOR THE PEG, I recommend a brim too
