Picatinny hands and terminal devices among other things.

I've been wanting some swiss army features in my hand for a while now. I don't think any of them could be printed, but you could make a hand with slots that could fit attachments.

Of anyone wants to have a go at this, I've got a few ideas for attachments...

Alligator clip (in the pinky)
LED
Knife
Snips/wire cutter (I use them in my job. No idea how useful it would be for others).
Bottle opener (in the bracer or palm?)
Tweezers slot? (See actual swiss army knives for what I'm talking about)

You could probably put one of those tools that pulls apart Lego too, for people that do that a lot.

I break hands and then tell you how I did it.

This makes all kinds of sense to me. More than anything, we should respond to the suggestions of the end users of the designs.
One thing that has slowed me down is lack of an attachment mechanism which is indifferent to scale factors. For example, a bottle opener can be the same size whether the hand is being scaled to 140% or 170% but the rail we currently use is sensitive in all axes. I suppose it would work over some range, but the idea of putting the load on thinner parts of the mechanism is not appealing. I may have overlooked something which has already been covered, so please share the links. I'm not easily embarrassed.

I bet a Tweezers slot could be designed into the top of the palm or somewhere on the bracer. :)

In a parametric model (e.g. Hand-O-Magic) we could make the rails a fixed size while scaling everything else. What would the desired dimensions be? I am sure that one of the OpenSCAD programmers here (me, Les, Nathaniel, etc.) could make this happen.

I've made an OpenSCAD model of this idea with slightly modified rails and a newly designed palm. It's not perfect yet but here's what it looks like!
