This is a Tabulate shopping trolly adapter
How many of us use an app on our mobile phone tto create a shopping list, but pushing a trolly holding the phone and filling the trolly is never easy
This adapter locks into the coin slot used to release the trolly so as well as replacing the coin it also can not fall out once in place, keeping your expensive telephone safe.
I have made a Euro adapter a pound coin adapter and an American quarter adapter depending in which country you live and shop.
Once printed assemble the two part with a drop of super glue and off you go shopping.
