Safety Key

A safety key that can turn on and off all shop tools in a workshop. I have tried this key on all kinds of tools of varying brands and it has worked on every single one.
The model should only be printed solid to ensure the longevity of the model and its strength as well.
It does 100 percent of the function of a real safety key and has the exact same dimensions.
It takes around 10 minutes to print and should be printed rather slowly under around 20mm/s. Other than that this is an extremely easy print and will print under almost any conditions.
