Vacuum Bag Valve Spacer

For those who use vacuum bags for storing filament know the struggle: You try to suck the air out with the hand pump but the bag sticks together and no air can get out.  This disk allows for unrestricted air flow within the bag.

Instructions:

1. Print
2. Apply your favorite double-sided tape to the flat side of the print
3. Center over the valve and tape into place
4. Pump the air out.
5. Pro Tip: Press on the valve to re-seal it properly. 

I found the first 3-4 pumps are difficult until the valve opens, after that it is easy.

Enjoy!
