After trying to work with the original models I found that the 2 models provided were either too Thick to fit the lock slot or too Thin and flexed too much to allow proper use. I modified the model in Tinkercad and added some triangular points from the handle to give the pick more strength. Then I found that the tension bar would not fit properly into the lock, it needed to have the strength to provide the tension to the pins, so I shaved off some of the bar that enters the lock. this allowed the tension bar to retain its strength and still fit in the lock. Hope you find the modification useful. I tested this with a master lock in my home and they function as expected..
