The GPX does not have a regular handlebar, which makes the installation of a phone holder impossible.
This bracket is intended to be placed below the ignition lock, reusing the original screws holding the plastic cover. It is not a phone holder, but rather just the bracket for one!
There is a little hoop at the bottom of one leg if you want to attach a string.
Preferably print with PETG, or anything that's not PLA really.
The author marked this model as their own original creation.
