Dampening Feet for Wesco Trash Can Insert

Really simple solution for a really annoying problem. I wonder why Wesco doesn't supply something like this by default with its trash cans. The inserts out of sheet metal sit directly on the ground, thus making a horrible noise whenever the trash can is being emptied or moved around - preferably in the middle of the night. 

Print a bunch of the feet out of a flexible material (TPU) and snap them on. They fit the insert of my Wesco “Kickmaster” trash can. I would expect that the relevant distances don't vary with their other models. But I am interested to know.
