Garbage bag anti-slip

Don't you just hate it when the garbage back slips down inside the garbage can!! I got tired of this and shortly after getting my 3D printer I decided to make this little gizmo to prevent this terrible tragedy from ever happening again. Ok, maybe it's not a tragedy but it can be messy. :-)

Just print a few of these in PLA and clip them on to your can. I would do one first since not all cans are created equal.
