UK Lightswitch Tab Fix

thingiverse

This gadget attaches itself to the tabs on a UK backbox, providing a fresh screwhole for securing a lightswitch. It's especially handy for fixing stripped holes. At the rear, it requires an M3.5 (standard electrical) nut, which can sometimes be tricky to locate, but is generally easy enough to find online. You might manage without using a nut at all, as the screw will create its own thread in the print if needed.
