Excellent build and documentation newly graduated Rocket Scientist!
This material list and your build thread are invaluable for folks considering their first build!
As Master Builder Peter always says, "Follow a proven plan and get proven results"

Looking forward to your second, third, and fourth build!
Your diploma, lab coat, and pocket protector will be arriving in the mail as soon as we have such things!
Until then you may proudly use the title of Journeyman Rocket Scientist and wear your Dragon Technology staff shirt!

It is truly an honor to wear my Dragon Technology staff shirt as I lounge and enjoy the warmth of the newly fledged dragon. I'm anxiously awaiting the lab coat and pocket protector addition to the DT swag.
