Vertical Blind Replacement Gear

I have an old vertical blind system that uses one of those metal ball chains to control the angle of the blinds. After so much time, the gear has stripped and become semi-non-operable so I modeled this replacement based on the original and it actually works (got it on the first try, no less!).

Anyways, sharing it with the universe so someone out there doesn't end up throwing away their vertical blinds just because of this one failed part.

If you found this useful, it would bring me great joy to see your work - so be sure to share. :)

Or, better yet, please feel free to dump a bitcoin or two here:

... include a note to the effect of "Hi 3E8, thanks for the gear for vertical blinds thing... my life has improved five-fold on account of it and please accept this paltry amount in gratitude".

You're welcome! (in advance) :D

Also, feel free to peruse my other submissions which are almost as varied as they are many:
