Extend-a-Switch Extender
thingiverse
I needed to extend a light switch vertically a few feet, and the arm on the Extend-a-Switch wasn't long enough. However, they came in a 2-pack, so made a fitting to join them together to make a super-extender, and it does exactly what I need. It's a tight fit, which means it feels very solid even though you're toggling over a relatively large distance. Make sure to put the slide on the upper portion (which you can stick to the wall to stabilize the long arm) before affixing the arm into the coupler. This coupler is designed for this extender: https://smile.amazon.com/gp/product/B01HHQRH96 .
