Sure, I can't do it now because i'm super busy with final exams, but in the meantime I'll say this:
The torque damper replaces the output gear on the gearbox ( the larger gear ). It is just two printed parts [ Labeled "torque damper" on the downloads page ] and a spring [ linked in the BOM ].
They go together in only one way and that can be seen in the YouTube video at time-code 1:06: https://youtu.be/fneoYrtdVjo?t=65
Let me know if you have any more questions, you can also email me--I'l DM you my email address.
