DESIGN FOR THE THIRD PRINT, NOT THE FIRST
Nobody gets a functional part on the first print. What separates a fast project from a slow one is whether the model was built to be revised. Sketch relations that survive a dimension change, features ordered so a wall-thickness edit does not blow up the tree, and mating references that point at geometry you will not delete. I plan three physical iterations into every quote. The clients who are surprised by that are the ones who have been burned by a shop that promised one.
