What part would you want to see made, and what should it cost?

Hi all, I'm Ali, the maker of SistematikWork.

It's a free tool where you search any part and get its full manufacturing route, from raw material to finished part, plus a should-cost estimate and the materials and tolerances that fit.

I'd love input from the engineers, makers and buyers here: what part would you look up first, and what is the one thing you wish was easier to find out about how something is made or what it should cost?

Try it free at sistematikwork.com and tell me what is missing. Honest feedback very welcome.
