Do you have a place already open?
Not on computer with Studio so I can’t double check my instructions.
Sorry, my bad.
In the Models tab at the top of Studio click on the Advanced tools ‘Model’ icon. Then select the file I sent.
Thank you! 
No worries!
If you want to fine tune it just go into the script and you can change the Spring strength, the Motor Velocity, the acceleration and most of the Constraints Properties there.
