UK Single Light Switch Cover

After installing smart lights, and putting a couple of smart buttons in convenient places around the house, as well as a couple of Alexa's, I thought the days of hitting the light switch was over. I quickly discovered though my family kept, out of habit, turning the lights off by the mains switch and so I was no longer able to control my lighting through routines and voice commands. I modelled and printed this pressure-fit cover, that should slide on and stick to any UK single light switch of dimensions 86mm^2 Hope this helps someone out as much as it has helped me :)
