Thank you Ivelin. So obvious and staring me right in the face. I posted this code into another module and it called the form:
#import the Userform Class
from UserForm_MB2 import GetUFData
form = GetUFData()
if form.ShowDialog() == System.Windows.Forms.DialogResult.Cancel:
print(form._num_Ply)
print(form._num_Length)
print(form._num_Width)
print(form._num_Height)
print(form._num_HingeOff)
print(form._num_ClampOff)
print(form._num_NumTog)
print(form._num_NumHinges)
print(form._cmb_HoleType)
print(form._num_HoleD)
