Summary I modded this existing scope by removing the sights and adding my own. i also corrected the dimensions of the rail mount to eliminate all the post processing that was required to get it to fit. Print it Vertically and it comes out great. I designed the reticle as a separate piece to be printed out of glow in the dark material and then glued in. Its profile fits the ID of the sight perfectly. Credit to Kitka for their scope I found here : This thing was made with Tinkercad. Edit it online
