I was tired of trying to find random objects to try and unlock the earth input of my UK electric sockets in order to get my european plugs to fit, so I created this.EDIT: Just updated the file. The base is sturdier now WORK IN PROGRESS: The UK Pin Keychain has a hole that should allow you to pass a keychain through it Printed using a replicator with these settings: infil 10% layer height .27 shells 1 feedrate 40 travel 50 no raft HBP 115 Just push it into the top socket (earth pin) and plug in your normal european 2 pin plugs! feel free to remove the pin once your plug in in the socket. !! warning !! make sure you know what you are doing! this method will not protect your electrical devices from any kind of surge or fault!! But if you are desperate like me, go ahead EDIT: Just updated the file. The base is sturdier now WORK IN PROGRESS: The UK Pin Keychain has a hole that should allow you to pass a keychain through it
