Vacuum storage bag saver

Use this vacuum storage bag protector when using a storage bag that is not full, or to make sure air pressure (or vacuum?) is more regular or equal.
I used brims, and printed upside down. My printer did not require support but you will have to test with yours. The hole/support at the top is for ~36 mm valve which is standard on Space Saver or Amazon Basic bags. You can print at > or < 100% if you valve size is different. Dimensions are not critical.
