For like a $.5 part from McMaster? Are you on drugs?

McMaster is "expensive" but it isn't like they are charging a crazy amount of money. They are just expensive.

I still use them over randos tho bc I know I'm going to get what I ordered. I never did not, but if I did, I'd have the correct part maybe even same day.

The cost of the part doesn't matter. The cost of my time does.

For common components, I need a parametric part so that I can instantly change the length, size or type. If my M12 becomes an M16, I want all the taps and C'Bores to adjust without any further input from myself.

For more expensive parts, it's nice to have a homegrown parametric part to minimize potential missorders.
