About this 3D model

This is my first design for a NERF silencer/flash-suppressor. The narrow end fits over the bayonet-style mount on some NERF blasters and twist-locks. I've only printed about 40 mm of this. The inner connector diameter was too tight to fit on my blaster with out filing. That may have been a printer problem. The wall is also very thick. I abandoned this design modified it to be a uniform diameter. Designed in OpenSCAD
