Our team doesn't actually have it's own 3D printer yet, so far we've been borrowing other people's 3D printers. There are a lot of parts of the vacuum that were 3D printed though, one of the most notable parts that was 3D printed was that black plate thing. I forget what the plate specifically does, but I think that it's an air release of some sort. There's also a few connectors for the vacuum that we 3D printed too because we couldn't find anything that would work for that.
