DIY Blowdart Gun- Handle, Connector, Mouthpiece

I am working on a blowdart gun that is partially 3d printable, you will need 2 13mm aluminum tubes. That is all you will need for a functional blowdart gun. The Design could be improved by adding a foam grip! will be updated with the final piece which is the mouthpiece soon. I will also be adding other accessories as well shortly. if you test print these parts please let me know how they came out, my 3d printer is down and I am working on fixing it. thank you for your interest and patience =]
