This is just a simple ring that allows you to easily and securely use a 13 gallon kitchen bag instead of using the expensive single use bags or the annoying tear and tie off bags. We get bulk 13 gallon bags very cheap so this was a great upgrade to our diaper pail. Also the trash bags allow it to fill up entirely actually using the space and not needing emptying so often.
I printed mine in PETG and it works perfectly, just put the bag through the ring and tuck the edges around the ring and clip the ring into place under the tabs in the pail. PETG works great since it has some flex.
