plastic bag evacuator

thingiverse

This device is designed to remove air from plastic bags by forcing it out through a small opening. By applying the venturi principle, the suction created at the conical entrance effectively extracts the air. The efficiency of this process is roughly 4:1, meaning that for every 4 liters of air blown through the nozzle, 1 liter of air is removed from the bag. This device consists of two main parts. After printing and cleaning, these two components must be joined together using glue.
