Jerry,

Thanks once again for your expert information! I appreciate having you on this forum to answer questions such as these, as I recognize you were one of the pioneers of high power rocketry.

Jack,

I mean no disrespect for 3D printing and offering the parts you provided the files for on thingiverse. I am not trying to start or run a business, I just want to recover my expenses for the 3D printing of these items. I see this as a way to make these rare parts available to those who have graciously helped me on this forum (like you and Jerry). Please accept my humble apologies if I have offended you.
