Looking for part

[Michael Horvath]

Is there a stud that is sort of the inverse of 87087.dat "Brick 1 x 1 with stud on 1 side"? I.e. a stud that has a socket instead of a stud, but in the same location? Brick 1 x 2 or Brick 1 x 4 versions would be okay too.

Thanks.

I don't think so. 6541 (1x1 technic brick) has a hole all the way through, and 4070 (headlight brick) has a socket on the back. I think those are as close as you can get.

Is it safe to insert a regular stud into a technic hole? Is this a legal/recommended connection?

I believe that LEGO considers this to be legal for 1 stud in 1 technic hole, but not legal for more than one. So they would never release a model with a 1x2 brick attached to the side of a technic brick, but might with a 1x1 brick attached in this way. I could be wrong about this, though.

Yes, this is correct, and even used in two of the upcomming sets next year.
Look at the headlights of the tiny truck, 42084 and on the trash compactor, 42071

However, the two bricks, 87087 and 6541, differ in the position of the technic pin hole and the side stud by 0.1 mm.
Read more here (point 4.3), or make a test assembly in LDD.


The only true connection I know of is the backside of the headlight brick and the taller "Piece of Resistance", 15444.dat

This reference is confusing in that it uses millimeters whereas I think in terms of LDU where 1 inch equals 64 LDU. (Which is probably not true either.)

Thanks! I might have used the technic part instead, since the 0.1 mm difference does not appear in the LDraw technic parts (but does exist in LDD). Sadly, the headlight is inset on one side, and the gap is clearly visible from a distance when placed among regular bricks.

Has TLG ever explained why they chose to create the 0.1 mm difference in technic parts?

Well, there is some sort of explanation in these:

"When did LEGO decide that it was okay ...."
"Stressing the elements"
