@valleyforge as someone who's spent the last couple days dealing with my 3D prints delaminating, collapsing, and warping, the idea of firing a 3D printed gun is terrifying. I would be amazed if it didn't come apart and at least break a finger or embed a bunch of plastic fragments into my hand.

@valleyforge Yep, that looks a lot nicer than my Printrbot Simple V1. I'd still want to do a lot of test prints to gain confidence in the print quality though.
