Hey guys, Long time lurker here, first time poster =D I wanted to see if anyone have any suggestions on what I can add to make a box air tight. I was thinking of 3D printing a box. a Lid and the actual box itself. Customize it so that my containers can fit in side, + my tools and devices in certain spots. However 3D printing it probably won't make it very air tight and won't have a lock as well. So I Was thinking if anyone knows a way to make it a bit more air tight. My only idea is to put rubbery parts on the gap of the container, and find some way to pull a lock from the top to the side just like a cookie jar. Any other ideas would be appreciated!
