Four Mad Men here, you can call me 4MM for short. Thanks to Tholian for the invite. I used to build models when I was younger but haven't finished a kit in over 20 years. Started one last year but have yet to get very far with it.
They aren't platic or resin but I do make 3D models. My avatar being one small example of my work. If there was a club for starting a project and never finishing I'd probably be the Grand Poobah or something.
