Here is a quote from Dan on 11/15.
I did ask if they might be willing to engineer a single vent option into the filter plastics, but got no response, so don’t think that is going to be there day one, if ever. It might work to place the 'Forge onto a vacuum table of sorts to suck the filter’s output out, but anything easier will likely need to wait for a 2.0. I am hoping it works better than some people are saying it will, because I simply don’t have a good way to vent this thing.
