3D Printed Adapters for Koppa Trajectory Spheres

Post by 3DForensics »

Hello All,

I know some of you on this forum are using the Koppa trajectory spheres which are made to fit with a 1/4" trajectory rod. However, I ran into a situation where a smaller calibre was used and the 1/4" rod did not fit through the bullet hole. The next size down is a 3/16" rod but unfortunately, the spheres need to be secured with tape or by some other way on the smaller rod.

I decided to remedy that with a very simple adapter/reducer that attaches to the Koppa sphere and fits the 3/16" trajectory rod securely.

Have I mentioned how much I am loving my 3D printer??

Cheers,

Eugene
