Universal 'Robotic Arm Gripper' Bracket Connector

After downloading the ‘3D printable robotic arm claw gripper' by Juergenlessner and 3d printing it, I found the original connector from the ‘gripper' to the robot arm bracket to have very limited functionality.
As I wanted to connect the ‘claw gripper' to a bracket that had a servo within to facilitate a wrist turning function, I designed my own universal connecter in tinkercad to be used with this and other similar jaws, with or without a servo as shown.
I added another bolt hole to the core platform to give a more rigid connection.

The modified core platform and bracket stl files can be downloaded from here, and the other parts of the 'Claw Gripper' via the link to the original on the left.

The video below should explain:

I hope that it is useful to others.
