Vacuum pump holder

The vacuum pump holder is a simple tool to help you with removing air from reusable bags for storage your filaments. No assistance needed - it allows hands-free operation. Simply place the bag on the stand, and the vacuum process will occur automatically. You can do anything else while pump is working. It never falls down from your desk again ;-)My profile is high material-saving (less than 50g). There is “lightening infill” only. It is allmost empty as possible, like you can see on my photos. Only one support - easy to remove. And it is strong-enough, I use three perimeters for walls, 1mm on top/bottom. If you have this pump like me - enjoy ;-)Sorry for my English.
