Gas pipe key sleeve replacement part

I don't know if anyone else will ever need this, but I'm posting it just in case with the sketchup file included.
Basically I had a metal sleeve that fits into a hole in the floor in which the gas valve sits for turning on the fireplace with a key.
My little boys like to reach in a pick up that chunk of metal. And they are at an age (1.5) where they like to throw things.
So I printed a plastic version of the metal sleeve, making it much safer!
Printed great. I did .2 layer height.
