#605: 'Illegal' part connections

As requested by a fan on Instagram and because 'illegal' techniques are a heavily requested topic for discussion, here is a collection of 'illegal' part connections.

For those that are not aware, a technique is classed as ‘illegal’ if it puts stress on the elements used; they are avoided by LEGO designers as over time they would cause the pieces to deform or break.

The images/connections are from a presentation given in 2006 by LEGO designer Jamie Beard and although some of his points are now probably outdated, we believe that these connections are still classed as illegal. Check out the presentation here:
