Yea understood all good. I just don’t really use any of those 4 currently

FYI, these are the current options for social networks

I go to sleep every night listening to history documentaries, spy, mafia, religious history, etc with the audio only. As long as the voice is good and not overbearing background music or effects, it puts me out super quick and I slowly learn a lot

There’s a professor and his research group at university of Michigan that does compliant mechanisms that u could check out if they’ve got something. It was a while ago that I applied there so possible he moved but still worth a check.

I’ve never used freecad as I’ve always had access to a cad program thru either school or work. One option that’s not free is to join a maker space that has better cad programs or just torrent. But you’re definitely in need of FEA for the bistable part

Hopefully
