Endurance Laser 9mm Lens Flange

This is for the Endurance 10 watt laser to accomodate the G7 lens which in my case wasn't in the right focus range just threading it into the laser. The threads are 9mm x 0.5 which is very fine and may need to be chased by a tap. There are 2 versions, one that has a bit of an extension where the lens threads in. I just used that to align the lens the first time so I didn't cross thread it. After threading I removed about 2mm of the extension. It's connected to the laser body using 2 M4 x 10mm sc
