I do, but not every time. I got a DMCA takedown notice on one replacement part I designed. I challenged it and got it reinstated, but it left me a little bitter. Regarding spending hours on design... yeah, that part is a drag. I've done this enough times now that I'm just a lot faster than I used to be, and I also have a pretty good idea of what tiny portions of a design to print to do fit checks. But getting there certainly took some practice.
