Vacuum bag Vent Shim

Typically I store all of my filament in a vacuum bag especially after just coming out of the dryer. I always found the valves on this type of bag to be a pain in the neck. Sometimes they worked and allowed the air to be vacuumed out and sometimes not. So, I designed this shim to be inserted in the bag prior to sealing. Then simply align the center hole of the shim with the center hole of the bag. It doesn’t seem to matter which side of the shim is facing up.
