I made this prop for a secret Santa gift exchange and really like the original design. However, I thought it could be improved as the original nozzle size didn't match the size of the exposed barrel. So i made some changes to the nozzle by reducing it's scale until the radius' matched and cut a little bit off the top so that it also lined up. The footprint of the nozzle becomes much smaller than the end of the blaster but with the added angles I think it still looks fine.

Notes:
I printed the body of the gun sideways with supports and the nozzle and grip vertically due to size constraints. If you can print this vertically, do so, as your print quality will be vastly improved.
Gluing and painting
I glued the parts together with normal super glue before painting the part. I started with an acrylic primer, then spray painted a metallic silver layer before giving it a worn metal look. I finished by giving it a couple of coats of varnish. I've attached a tutorial for giving things a worn metal look. Please note that I did not make this video.
