Musk: Cybertruck parts must have ‘sub 10-micron’ Lego-like accuracy

In a leaked email to Tesla employees, Musk says that the Cybertruck needs to be manufactured to single-digit micron tolerance due to its straight edges.

Due to the nature of Cybertruck, which is made of bright metal with mostly straight edges, any dimensional variation shows up like a sore thumb.​ All parts for this vehicle, whether internal or from suppliers, need to be designed and built to sub 10 micron accuracy.​ That means all part dimensions need to be to the third decimal place in millimeters and tolerances need be specified in single digit microns. If LEGO and soda cans, which are very low cost, can do this, so can we.​ Precision predicates perfectionism.​
