Dillon 550 Borescope/Endoscope Camera Mount

This fits into the hole in the center of the Dillon 550 reloading die and is created to aid in determining whether powder is already in the case.
Designed to fit with the following camera: amazon.com/dp/B0CKQH4VZY
It will work with any camera with a diameter of .315 in.
There is a small lip at the bottom of the print designed to hold the camera and not allow it to fall or otherwise damage itself or the press.
I have included a picture of the view that it provides with the pre-installed lights on the press turned on.
