Some Assembly Required Engineer T-Shirt, Exploded View Bolt Blueprint Tee, Machinist Gift

Every engineer knows the feeling: five parts, no instructions, and one extra washer that's "normal." This tee draws it the way we'd draw it at work, as an exploded bolt assembly with balloon callouts and a parts list. Tolerance Stack is made for the people who hold the numbers: machinists, CAD jockeys, quality inspectors and the engineers who have to explain the drawing to all of them.
