Part 4070 differences in BI - Peter Grass - 2025-10-30 As mentioned in this old 2014 thread, the real life part and the part in BI have a side stud protruding over the regular 1x1 brick dimensions which was never implemented. It probably should be though since it would be easy to make a model that is unbuildable in reality due to this. https://forums.ldraw.org/thread-12698.html?highlight=4070 There are also a few other differences too in more modern revisions like how the internals are arranged and the internal circular hole depth. It also has those triangular parts which are likely to help hold a bottom stud a bit more securely. On the right is the BI part and on the left is the ldraw one.  I've attached the latest version of the BI part. RE: Part 4070 differences in BI - Chris Böhnke - 2025-10-30 I assume part of that change has been made to prevent those "slotted" versions from appearing. The original geometry makes part of the front so thin, it had a high tendency to fully cave-in. RE: Part 4070 differences in BI - Magnus Forsberg - 2025-10-30 Mainly due to the difference between reallity and the ldraw standards. An ldraw stud is 4 ldu high and have a diameter of 12 ldu All studs in ldd data is 4.45 high and 12.5 dia. To fix this we would need to redesign all parts, and make room for a taller and bigger stud. Remember, you are not allowed to scale the stud primitive.
