For citizen named "lowlight". Added a slight modification to the design. This will make it harder for the switch to accidently be turned off by adding support against the switch arm.
I have a problem with people turning off light switches that for most part need to stay in the on position. If you have a boiler switch or front door light that you like to keep on, this device will help remind your busy fingered friends that this switch is not to be touched. Although the design allows you to over-ride the on position by moving the arm out of the way and still turn off the switch.
You need to print with support there is a detail the has a cut away to clear the switch area.
I also included the CREO .pk2
