Remixed from this 8-channel aspirator model (link) Particularly useful when handling single-clones from a single-cell sort. Usually, outside wells are filled with water to increase the humidity, and only wells between B2-G11 contain cells.

Version improvement: I found that some of the sizes wouldn't print well with certain settings, so I increased the margin for tolerances. I also found that the tube piece could sometimes go in too deep and block the vacuum, and I changed it to prevent this.
