Getting a lot of requests for Metroplex files so I'm starting to put them up for sale - first is the knees. Later will come hands and ramps. Generation Metroplex knee swivels I'm not selling parts anymore. I still design from time to time but now I just put them up on thingiverse/3dcults for people to print on their own. Excellent printers are so cheap these days and free/cheap designs so plentiful there's no excuse not to own a printer if you have even a passing interest in 3d printing. We have entered a new era of DIY prints. I rarely take requests. This is a hobby I do when I feel, not a job, so any requests will probably be ignored.
