Login with my Xometry account Hi, 
I’m working on a small metal housing (around 120 × 80 × 40 mm) that will be 3D printed with DMLS for a sensor module. It needs threaded M3 screw holes and a flat mating surface. For those who’ve handled similar applications, what tolerances should I expect on the printed holes, and would you usually machine the flat surface afterwards to get a reliable seal?
