Mouth suction adapter for freezer bags

thingiverse

For quick and dirty vacuum sealing of frozen goods, one simply sucks air out of the freezer bag with ease. However, doing that directly by mouth is a serious health risk. This adapter comes to the rescue. Zip the bag almost shut, leaving just enough space for the eye-shaped part of the adapter. Then, press the bag around this part with your fingers. Breathe out, put your lips on the straw part, and suck air in from the bag. Quickly remove the adapter and shut the bag. I include three versions with different lengths of straw/tube to suit every need. The one shown in the photo is a little too short for the pictured bag, but don't worry, it still gets the job done. Print at 100% infill for best results. I had some trouble with Slic3r leaving holes in the thin portion - the holes were obvious in the preview. To solve this problem, try playing with the layer width or increase the minimumWidth parameter in the Customizer. This uses and bundles my Bezier library, which can be found at [Bezier library](https://www.thingiverse.com/thing:2207518). **Updates:** * August 7, 2019: By default flattened the straw profile (use the holeAspectRatio parameter) and uploaded the flattened version of the stl.
