centralized vacuumer wall plug

cults3d

i have a centralized vacuum dust cleaner from a known canadian brand, the vacuum cleaner is ok, but the plugs wear down real fast, so i designed my own, to cut down replacement cost.... since i only use the "construction" variant (without shiled to hide the plug) i desinged only those, but its done in openscad, so you can add your own! if there's interest i can open up a git, would be nice to have some cooperative work (instead of some remixes... that are hard to follow and mantain....) so have fun!
