Lock Pick Tensioner BOK

Functional lock picks tensioner: 1mm or 1.4 mm tensioner thickness

1mm fits more locks but is less rigid than the 1.4mm version

Works best on smaller locks with less opening torque
 

Use stiffer materials such as PLA, PLA-CF. 

ABS or PETG are more flexible, which is bad for printed lock tensioners.
