Does anyone know of a source for the male portion of the garmin 1/4 turn mount? Just looking for the small portion to attach to a phone case as I currently have a need to have quick access to my phone on rides

I found this on Amazon but would have to grind two of the tabs off and it takes a month to get to the states from Asia

Figured someone might know of a shop that could 3D print something similar or has already done so?
