Name Batch Autorewinder Remix 2

I really like the idea of using a name batch reel to drive the rewinder, I hope the metal spring keeps the tension for a longer time period compared to the printed spring. I did a few test prints with this rewinder and so far it worked perfect.

Changes:
I just remixed this into one part. Just cut away the batch coupler an use the remaining plastic as an insert.

I also changed the the transmission ratio a tiny bit and used a knurled pattern for the clutch area. I attached the f3d file for easy remixing
