Impala Phone Holder 3D print model

Thanks for offering this, can you share what phone holder you designed this for? I've tried about 7 different ones and the ball diameter seems to be just like a mm or two small, so the mount doesn't securely support the phone upright. The stem of the mount could use to be a little longer as well, the back of the mounts seem to hit the dash trim before allowing any real pivoting toward the driver seat.
