I had always wanted to build my own 3D Printed Nerf Gun. I found some heave springs and when my 3D printer arrived it was finally time to start this project. Subscribe to my second channel: First video coming soon!!! A good 3D printer: this 3D Printed Nerf Gun uses a heave spring power to power the piston . And yes it is pretty powerful and it hurts like hell when you get hit by this one XD. I tried to build this 3D Printed Nerf Gun 100% 3D printed. But unfortunately this didn’t work. The surface of a 3d printed parts where not smooth enough to get an airtight seal. So in the end I used my lathe for the internal parts. When the CAD design of the 3D Printed Nerf Gun was finished I started with test printing al the mechanical parts in test prints. I took several test prints to get the trigger mechanism w
