Filament bag Vacuum disk

I use small plastic vacuum bags to store some 3D printing filament rolls that are sensitive to humidity. The Vacuum bags use a little valve that opens to let air out when a little pump is used. The problem is making the pump open the valve efficiently, especially when the bag contains a roll of filament, filling it to the limit. This little disk will let you apply plenty of pressure to get the valve open. You might even hear a 'pop' when it does. The disk uses 6 grams of plastic. PLA is perfect. Alignment with the center of the valve does not have to be perfect. As long as at least one hone is aligned with the center of the valve, it'll work great. I chamfered the perimeters to prevent damage to the bag. The side with the round 'channels' goes on top (as in the first picture), facing the bag's valve. Video at https://youtu.be/1--grYH1BMM
