eSun Vacuum Helper

If you have one of the eSun vacuum bags for your filaments, then you will understand how difficult it is to actually pull a vacuum with it, even with the electric pump. They want you to put it on a flat surface, but that just blocks off the valve on the bag.
I came up with this tiny puck that you put in the bag under the valve, then place the vacuum pump over it and done! Air flows through the side holes and up the middle and you get your bag vacuum packed in seconds. Im not sure why they didnt include these in the box!
Any questions or comments, drop me a line.
