Summary

For those trolleys that don't require you to insert a token or pound and you can simply use this and retract by pulling back at a slight angle so need to leave in the trolley whilst shopping- I always return the trolley and don't leave it randomly abandoned in the car park :-)

I've printed these in PLA and TPU and I prefer the solid TPU as I like the flex and the item still functions

I have uploaded another design that has a fob and detachable token for the alternative trolleys
