/*
    Color code your keys, to make it easy to pick the right key.

    Print many covers, each colour coordinated with the door colour.
    If all you doors are the same colour, paint them ;-P

Print Notes

    Use a brim, as there is very little bed contact without a brim.
    Use high number of perimeters, as we don't want any infill, but do want it solid.
