gosh no.
- switches and encoders are official CAD parts from suppliers
- PCB is an export into Fusion from EAGLE
- raspi and all components on it is a model I found on Grabcad.
- audio jacks on shield are models I made myself from the drawings for those jacks
- I think screen might be an official model, or one I made from a mechanical drawing - can’t remember.
Meaning the only thing I actually made for sure is, you know, the top/bottom panel and the stereo jacks. Grabcad is handy, but you have to be prepared to wade through some less good models to find better ones.
In general, I only use Grabcad for faffy things. I’ll definitely use manufacturer’s official STEP models if they supply them, though, that helps a lot, and PCBs I either export from KiCad as STEP (nowadays) or (if I’m working with an EAGLE board) direct from EAGLE into Fusion.
