First prototype of Nerf style dart shooter with a ball connector to fit into Polypanels Ball and Socket or the Polypanels Ball and Socket Extensions which will require an internal spring between the bolt carrier and the end cap. Very simple trigger mechanism for proof of concept.
UPDATE: I have uploaded v2 files which have improved the barrel, and the bolt carrier considerably. This one shoots a dart all the way across my room!
If you have suggestions on how to improve trigger mechanism or design, leave a comment below and I'll be happy to tweak and upload additional designs!
Print the barrel in the provided orientation with support touching build plate only. I increased my shell wall count in order to maintain strength of the ball joint.
