I'm feeling motivated for some strange reason ........
Give me some examples of models that you wish you had access to and I'll make an attempt to post some of them on the FirstCadLibrary.
Please keep it on the component level. I probably won't have time to model that 12 speed gearbox you've been thinking about.
If I can find the part in my junkbox - or - get enough data online, I'll model it.
