So long story short, I have an incredibly rare rifle (Z-M Weapons LR300) that uses a charging handle that is similar, but also different than a standard AR-15 charging handle. Mine was damaged, and I need one 3D printed out of plastic in order to test fit in my rifle.

I have a friend who also happens to have one of these rifles, and he helped me make this CAD file.
I would like to make sure that the measurements in the CAD fiIe are good to go; then I'll need a machinist to make one out of 7075T6 aluminum.

Does anyone have a 3D printer, and who is willing to print one out for me?

Also, does anyone have a recommendation for a machinist who can make something like this for me? I would want probably three of them.

Thanks!
