I wanted a way to make custom sized vacuum bags (space bags?) for storing filament, and decided to try model and print one myself.

It works pretty well, though it is not perfect and takes in some air. The SCAD source is a bit of a mess as usual, so sorry about that.
The rubber seal is cut from a silicone pot holder. It's the same kind gregfrost (and I) use instead of springs to tension the idler on the extruder. http://www.thingiverse.com/thing:17030
