We use GRIPGO phone holders in our work vehicles and while they are a decent phone mount the suction cup windscreen mount is the weakest link in its design.
I have Remixed a Garmin GPS holder that I printed for the same reason with the suction cup detaching.
This mount allows the full rotation and movement of the arm of the GRIPGO to be attached to the Windscreen or Dash using a 3M VHB sticky pad (Same as GoPro). Attach the arm to the base using a m5 bolt and lock nut.
Cocoon Create ABS
Printed in ABS at 90% for strength as it's used in a vehicle. Printed on a Cocoon Create Touch at 240c/85c with a brim although it probably doesn't need one.
