It somehow makes sense to rename this part, but only if we also rename 4221.dat and 30198.dat. They should get sorted together. I would like to see something including the word "arm".
4221 "Arm Piece with Grab Jaw Holder"
4220 "Arm Piece Grab Jaw"
30198 "Arm Piece Grab Jaw Holder with Handle"

As this part is now here I like to see the circular edge corrected where not needed and also the bumps where this part will be connected to the counter part.

Also, the arm2 primitive is not actually a perfect circle - it does not mate up with a 4-4ndis primitive.

Any news on this part from your side?

Comments:
the arm2 primitive is IMHO not the right primitive here, as it contains edges that we do not like here.
A quick look at LDStructure tells me that this is the only use of arm2 where the edgelines are wrong.
I would suggest to create an arm3.dat do have the edgelines at the base just the other way round for to have this primitive work also on other parts.

There are still possibilities for improvements.
f.e. the surface on the opposite side of the arm is made from one quad and therefore it bleeds on the sides.

Duplicated surfaces. Both a box- and a ndis-primitive?

I have to hold this part, because it seems, that it is wrong modelled.
Please compare with this picture:

Good catch!

Are you sure of this design?
4220 in LDD have a different position of the jaw grip bar. I think it should be longer than it is.
If I measure the LDD-part I get 22.5 ldu between the rotation points.

And it has a flat middle finger. Are there two versions?

It seems, that you are right.
The real part (with rounded middle finger) is exactly 15 mm long.
We have to make this file obsolete and I will create a new 2.5 LDU extended one - named 4220a.dat
Due to the fact there are pictures in the WWW of real parts with flat middle finger, I'll create another arm primitive and use this in a 4220b.
So this change will be fully backward compatible :-)
