Vacuum adapter

This is an adapter for vacuum bags for filament. For a long time I have been solving the problem that the bag was draining too slowly due to insufficient air supply. I drew two versions where V1 has a 31mm inner diameter and V2 has a 28mm inner diameter. I believe that this model will make work easier for many people and make it more pleasant to extract air from the bag.Printed on bambulab x1c.layer height is 0.20mm and infill is 15% adaptive cubic.perimeters are 3 top and bottom, 2 walls.
