UK shopping trolley key with tension spring and keychain hole

thingiverse

This UK shopping trolley key is redesigned with a smoother push action on the slider, a tension spring on the reverse side to keep all the parts together and a keychain hole. Push the slider forward, insert it into the shopping trolley slot, wait for the click, then pull the slider back (this decreases the overall width) then remove the key. No more money needed, no more walking away from your trolley forgetting there's a pound coin inside. Feel free to leave comments. Happy times.
