I think the walker would be a blast to shoot. Didn’t know they sell it as a kit. At over 15 inches long and 4-1/2 pounds, they’re the steam locomotive of hand guns.
I’ve found the stl files to 3D print one, as a plastic model obviously, but would still be neat as a wall hanger. This guy does a hell of a job with painting his. It looks damn near real.
So yeah, I guess that’s one of my hobbies, cad and 3D printing. I mostly draw things up and print them to replace broken stuff. I have a friend that restores high end vintage stereo equipment. I’ve done several gears for turntables. Latest project is a lever arm type of thing that returns the tone arm for a pioneer turntable.
