Light switch extension by Peterthinks May 27, 2013

Description

This thing was made with Tinkercad. Edit it online tinkercad.com/things/h7mfIdrCtwr This is an extension so kids can turn their light on or off, quite honestly I was a lazy Dad and my daughter refused to use the bathroom at night by herself. She was always waking me up just to turn on the light so she could pee. It would also be handy for people who are in wheel chairs who can't quite reach high enough. Make sure you secure the strings to the wall with the grove plate and screws to eliminate the choking hazzard. This should bolt right over the original light switch cover using the original screws. I have not tested this yet since my printer is not shipped but I have hand built one and it works. Pulling down on each end of the string will turn the light either on or off. You can also operate the switch normally. Hopefully I got all the holes in the right places. I would like to thank Autodesk for bringing Tinkercad back. You did a good thing.

Worked for us, but we had to increase the thickness of the main plate by 70% to keep the slider piece sliding without much friction. So I'd suggest increasing the depth of the insert in the main plate by 50-70%. We also needed new bolts (1" 6/32 was more than sufficient, 3/4" probably would've worked - our original bolts were 1/2").

I have a digital micrometer on the way and I will double check my measurements when it gets here. This thing will change. File is untested.

I flipped the groove plate over in the file so you don't have to print the face over an overhang.

Instructions

You need to secure a length of string to the square red plate. It's attached on one side by trapping a knot in the string in the hole in the middle of the groove. The string moves freely in the other groove. I added a purple line to represent the string in the pictures but it is not part of the print file, it is just there to show you how it goes together. I'll tinker with it a bit more when I have my printer but for now it's as is and untested as a 3D print file. This is designed to screw on top of the light switch plate, not to replace the switch plate.
