Body: <p>Different sources show different thickness for the wall. I've seen everywhere from 1.0mm to 1.8mm.

Comments.Text: Hi Mark, the [top-voted answer](https://bricks.stackexchange.com/a/295/56) in the question this image came from gives the dimension of the wall of a 1x1 brick as 1.6mm, while the technical drawing this came from was actually in mm, so the wall thickness there is 1.2mm.

  Different sources show different thickness for the wall. I've seen everywhere from 1.0mm to 1.8mm. I need to know with a high degree of confidence since I'm making an aluminium lego piece of a school assignment, so my wall thickness will be smaller. Because I only get to have one attempt, I can't try it with one piece and adjust the model for a second run.
