The wire frame garbage bag holder is made for bags with loops. What happens when I don't have any more of those? The ones that I buy in boxes are made for different garbage cans. A solution is to install a pair of these Garbage bag holders which snap on the wire frame. Tie a knot on the end of your bag and slide it in the notched hole. This one is made for 5 mm diameter plastic coated wire. If yours is different, modify the TInkerCad file here:
Add a bit of glue from a glue stick for better adhesion.
