The Many Faces of Treadwell

[TBOU]

These are awesome.  Have you seen any details on the multi-armed treadwell?  I’m thinking some slight variations would get it.  I’m assuming the multi-armed types are the same size.  

Any ideas on what they had at the end of the arms?  Most end effectors look like claws/grippers, one looks like a scoop, but some others look very different.

Has anyone from the mountain state droid group ever written up a build of their multi-armed treadwells?

I have seen some. I spend a lot of time looking at droids, though, so the specific what's or where's I often forget.

Now that we know what you're looking for, though, I'm sure people will start looking around and collect up what they can find.  Which multi-armed one did you mean, specifically?

Builds based on one of these, mainly.
