Parallax focus wheel for scope

A friend asked me to make a Focus Wheel for his "Southern Gun CO" scope on his air gun. I looked at some images and created this. The center hole is 26.7mm in diameter with 9 knurls. I added a 3mm setscrew hole in the side. It can be resized to fit your scope but the 9 knurls would have to be changed. I added a set screw to secure it. If you contact me I can make changed for your need. I also posted the wheel without any knurls and with a it has a 30mm center hole. It now can be modified to fit your rifle scope. I use TurboCAD. It does more than everything I need. I printed it on an Ender 3 Pro at 70% with no adhesion or support using ABS.

I custom made this alternate one for my Ruger Precision
