Well, as this piece is commonly used with the 2854, and that piece is already
in the vote in its own position, I would place the 2853 in the default position
easiest to use with the 2854.
That would require a 180 degree flip of the 2853 and a little adjustment to
space it properly so two connecting rods fit between the pieces.
I have included a file illustrating the approximate position.
This may not be the best position for it, but it is the best I can think of.
No matter what its insertion point, it will require some moving in a model.

Another question is the insertion point for the 2852. Having it vertical is
fine. The way you have it now works pretty well. A half step either way brings
it inline with the axle of the crank. Two steps fore or aft to position it the
other way. And it rotates nicely around the centerline of the ball, so placing
two rods is easy. I would leave the 2852 as it is now.

If you can't find the part number, just give it a temporary name. Before I put
it up for voting it will be reviewed and (hopefully) given a correct number.
If not, it gets the 3-digit number treatment.

I originally thought that the 2853, the axle #2 with offset crank, should have the axle oriented in the X-direction, as do all axles in LDraw, and that the 2854 should have the axle hole oriented in the X-direction, as do almost all parts in (...)
