Garmin zumo 3xx Navtower mount (12.2mm rod)

thingiverse

I purchased a Garmin zumo 396 to replace my aging 660, which was securely fastened to my navtower. Unfortunately, I encountered an issue when attempting to mount the new device because the cradle from the old unit has a distinct orientation, necessitating an adapter. My navtower rod measures 12.2mm in diameter. This mount should be compatible with the entire 3xx series, which boasts a different style of mounting compared to the 6xx and 5xx series. It's advisable to print this design using ABS or a heat-resistant material since bikes often remain in hot environments, and PLA or PETG may become significantly softer. This mount should also function effectively on larger rods with longer screws.
