I'm trying to use the scripts but I don't know that stl library to install Just running "pip install stl" gives me this error :
Traceback (most recent call last): File "c:\Users\User\Documents\GitHub\Transform\Scripts for Variable Angle\Transformation_STL_var_angle.py", line 2, in <module> from stl import mesh ModuleNotFoundError: No module named 'stl'
