Copy the scripts into this folder:
:RuntimePythonposerscriptsScriptsMenuPartnersDimension3D

NB: The new version still has a couple of bugs that were in the old one.

Line 819:
self.edit[10].SetValue(m[5])
should be:
self.edit[11].SetValue(m[5])

And

Line 901:
elif s == 24:
should be:
elif s == 23:

Remember indentation matters in Python if you're thinking of correcting it.

Thanks for those!
