Hello - I don’t know if that is the most up-to-up-to-date version - here is a plug-in version that is the latest that I have - not flawless either but I think it works.

FinTools.rhp (35 KB)

Let me know… the rhp will need to be unblocked in Windows, and then you can drag and drop it onto Rhino. FinTools is its command name.
