Printed the parts and one of the arms on the backside snapped off. This actually made installing and testing the opening/shutting mechanism easier. I'd suggest in a later revision to have one of those arms be a separate piece to be attached near the end.
Aside from this one thing, this model is absolutely bad ass, and has been a lot of fun to tinker with to assemble. Once I've painted mine up and installed a light I'll be sure to post pictures.
Thanks for sharing this model!
