In my house the AC works flawlessly, that is until you walk into my room. For some reason my room is a few degrees hotter then what the thermostat is set for. Because of this, I always have my fan running to circulate the air better. For my room I have a dimmable switch on the left for my lights and a normal switch on the right for my fan. Every time when I go to turn off my lights when I leave I accidentally hit the fan's switch also, causing it to be extremely hot in my room once I come back. So I set out to design a cover to place over this switch. A download is available at then end of the Intractable or on Thingiverse

Step 1: Render

I started by taking measurements of of the light switch I wanted to cover. I designed the cover to work with most switches. I made it so all you do is remove the top and bottom screws from the plate, add the cover on and replace the screws. When I first printed the model it happened to be just a little to long for the screws to fit into place. So I went back and changed a few measurements in the design. Since it was my first time creating a 3D rendering I was expecting some mistakes but was surprised it only took me 3 attempts to get a working design. I have learned working in Fusion 360 is a lot easier than it looks.

Step 2: Print

Just print the file and then remove the rafted to place on the cover. I printed in Glow in the Dark just because I thought that it would be kind of nice to be able to see the switches in total darkness.

Step 3: Use

After installing the cover, I quickly realized I wanted the ability to turn the fan off when I need to for when the weather for better. I ended up ripping the bottom tab off and only mounting it from the top screw allowing me to just swivel it out of the way then I wanted to change it.

<p>For paddle style (decora) switches like yours a simpler design (no 3D printer needed) would just be a flat rectangle of metal (like aluminum,or even a stiff plastic) with a single hole (think of the mounting tab of your design but longer).</p><p> You would mount it on the top screw and it would slide/pivot down over the top edge of the paddle, holding it in the ON position. When you desire to turn OFF the fan you would pivot the device enough to allow the switch to turn OFF.</p>
That would work but then my issue is I don't have any metal of still plastics to use. It was easier for me to render up a model and 3D print it off my printer. I don't have the tools to cut metal or plastic and make it good looking with no sharp edges.
Yes, given the fact that you have a 3D printer but, I guess, not a drill, knife and file/sander, then it makes sense to print this. :)<br><br>But, regardless of manufacturing method, it still holds true that (for decora style switches anyway) a flat tab is a 'simpler' design (not saying one is 'better' than the other, just 'simpler').<br><br>Yous could easily 3D print my suggested design, just take your design, delete the 'box' and bottom tab, and lengthen the top tab by about 2 to 2.5 times its current length - faster to print, uses less plastic.<br><br>
<p>Couldn't you just plug into an outline that is not driven by a switch?</p>
<p>A ceiling fan is hardwired on a switched circuit, not plugged into a wall outlet.</p>
