alt Hacker NewsSomething that took me years of working with custom plastic injection part experience to notice still kind of shocks me…
Legos don’t have draft.
That means nothing to 99% of you, but someone else here must understand what the implications of that are for releasing from molds at a mass scale.
Actually they do have a draft. The bricks are designed so you don't notice it, both by the draft angle being quite small, and the parting line is moved up slightly so by the time you get to the bottom of the brick you're back to the original width.
