yes, I am not updated on the topic. You're helping me to get back on
track. I'm sorry if that is disturbing for you ;) Please call me
Janek btw, because there's another Jan around here.

In the other email I was trying to find that plastic part and compare
with that other (trapezoidal) approach, but I didn't finish that today.

Thank you for the attached .pdfs.
