Cable strain relief wall mount

After having installed the IKEA Upplyst bed lamp in my daughter's room, I noticed there wasn't enough strain reliefs included and therefore my daughter was able to unplug the cord to the lamp. And since I couldn't find any way to buy more of the same or similar I decided to design my own. So this is the first iteration of that. I recommend printing it out of a material with strong interlayer bond like PETG at high temp, but it also works with PLA. Once installed its really sturdy.
