Work in progress :-) It's mostly there, just need to connect the tab to the body and add a few edge lines. Some details have been simplified in the interests of an easier life, but it looks reasonable IMO.

Couple of queries: I haven't modelled the interior - should I? The part actually consists of two pieces (plus wheel bearings and what I assume is a weight inside it) - again, I haven't bothered - should I?

If you are able to make all composite parts without destroying the part I would prefer to model them all.

I suspect the part is just a hollow box, so it shouldn't be too complicated to add the insides. I don't see any way of opening it up (it's probably glued).

Now with interior and other details :-) It's functionally complete, albeit simplified a little.

I've left out the lip on the top of the tab (looks more trouble than it's worth) and the indentation below it (not functional), and the interior is just an empty box.

The part origin is actually outside the part itself: this is deliberate! The idea is that the part can be dropped next to x433 and will a) line up vertically with the tab in x433's loop; and b) swing from side to side within the loop.

thanks for the explanation,
however, the vertical placement of the origin is still not okay IMHO,
I think it should be moved up to be at the same level
that the top surface has

I disagree. This part doesn't really 'sit' on the normal grid - you have to offset it vertically by 12LDU relative to x429c01.dat to get them lined up - and since the brick can't really be used for any other purpose I don't see the point of making extra work for the modeller :-)

I like the origin like it is here, as this way it can perfectly be used with the counterpart. Please downgrade to novote.

I still disagree with you.
This part needs to be properly displayed in inventories, too.
We have a policy that all parts that have an own file in PARTS/
need a proper origin. So does this one.

Which software do you use for inventory? As it depends on how the software show that part (based on origin, or based on bounding box).

Reviewer: Steffen
Certification: novote
Comments:
That question is not of relevance here: the software might
be configurable between (a) "use bounding box", (b) "compute top position by itself", (c) "use origin of file".
Using (c), the software assumes that all parts follow
the specified origin placement strategy of "origin is at top surface".
Wouldn't this file get that proper origin, it would look odd in such inventory lists.

I was just using this file together with x429c02.dat in MLCad.
After some consideration, I agree with you from the above discussion
that the current choice of X and Z makes sense.
The origin sits in the rotational center.
However, the Y choice simply is wrong.
When using this part with x429c02.dat, you need to correct that manually, and it is not even at the top.

I ask that it gets changed to be either chosen in a way that allows
immediate combination with x429c02.dat. But personally I would prefer
that the origin gets moved vertically to sit at the top surface as usual.

Just tried it:

1 16 0 0 0 1 0 0 0 1 0 0 0 1 x429c02.dat
1 16 0 0 -20 1 0 0 0 1 0 0 0 1 x946.dat

They line up perfectly.

i would have liked the origin at top better.

Is this part distributed without the wheels, or should it have a "~" prefix? Do we need a x949c01.dat with wheels attached?
