This is a really neat process, thanks for posting it!

Are you using Buna-N type of o-ring material, or does it have to be some other exotic material for this process to work?

As for the die, how did you decide on the dimensions for the triangular shape and o-ring diameter to use?


Edit: apparently I can't hand out more green dots for your post, but have to say that I love these threads that document building processes!
