Designed for the TP-Link Deco M5. There are other examples of this however I wanted to design one of my own to add to them. I'm not sure if some of the other examples are designed for UK plugs but a couple I printed would not fit onto the plug so decided to redesign from scratch.

I have split the holder and the socket ring to help with both printing and the affixing the holder to the socket. You could glue them but they do hold together so I haven't bothered.

Play with the orientation for supports. I have used a resin printer and probably didn't use enough supports but the print is still fine.
