I worked with in a garage where they employed someone to valet the hire fleet. He was incredibly slow but did a decent job. Half his wage was paid for by a government agency, he was originally on an unpaid work experience thing and the agency asked the boss if he would hire him. He said no so they offered to partially fund his wages so boss said ok. This is similar(better imho) but there are people you simply would not employ (unless you are doing it for charitable reasons) because you can get someone else for the same money.

As others have said, Freecad is actually really good once you get used to it. I use the real thunder fork for the sake of the Topo naming fix. I have also used openscad, but only if I'm making something customizable to share.

Same. I use torx for everything. Also gotta love the square Robertson ones, they're just not common where I live. I hate Philips, although for anyone not aware, there is a difference between posi drive an Philips and going to the effort of making sure you have the correct one massively reduces torquing out and damage to screw head.
