Decora Switch Extension

thingiverse

This was a quick remix of the fantastic original extension by @danmar. My youngest daughter is petite, and she can't reach the light switches to turn them on and off. So I modified the original extension and created three parts: a part that mounts to the light switch, an extension piece to lengthen everything, and then a pull ring that goes on the bottom. I use one of each part to get a good length for my daughter. She loves it and feels super awesome when she can turn the lights on and off all by herself. The openscad file generates all three components. At the top of the file are some variables that can be modified as needed. Set buildSwitch = true if you want openscad to generate the main part that attaches to the switch. Set buildExtension = true if you want openscad to generate the extension part. Set buildHandle = true if you want openscad to generate the circular handle part. Only set one of these options at a time and then re-render. I have included three stl files that work well with my north american decora switches. Print Settings: Printer: Kossel Mini Rafts: Doesn't Matter Supports: No Resolution: 0.2 Infill: 20-30% How I Designed This: I based the design on the original Decora light switch extension by @danmar but I removed the cross bar pull from his design. Then, I used the puzzlecut library from (http://www.nothinglabs.com/puzzlecut-openscad-library/) to create some interlocking tabs that could be used to connect all the parts together. I tried to maximize the build area on my printer so I could get the extension to be as long as possible. Everything fits on my 160mm diameter bed.
