trash bag hook for shelf pins

quick remix to add a shelf pin to fit in standard 5mm shelf pin holes found in my kitchen cabinets (and most others, in the uk at least).

pin is 5.2mm so might need some persuasion to locate but should hold well enough. print with some support or something- its an interference fit so doesn't need to be too exact in shape/size/finish, and finished looks don't matter as the pin won't be in view anyway.
