Better mechanical design of a umbilical connector?

[Andrew Greenberg]

Hi airframe-y people!

We have to redo our umbilical cord connector because we need two more
pins on it, and I don't like the current connectors we have:

- they're really expensive ($15 for each piece, male and female!)
- they're hard to solder
- while the ejection mechanism we have is clever, it scares me a bit in
terms of possible failure mechanisms

It could be that what we have *is* really good, and all we need to do is
rev it, but I'd like to maybe think a bit about a 3D printed system that:

- is extremely reliable
- "can't" bind
- is relatively cheap

I'd really like to move on this since we need it right away: if any
mechanically people are free this Friday, please come join us at the
hack day in 84 Lab (FAB 84) after 1pm and let's discuss the current
system, and ideas for better ones!

Thanks,

Andrew
