Bigger IKEA SKADIS top mount shelf with LED holes

I saw the bigger version of the top shelf which I liked because of the extra space it gives you, but I also wanted to be able to add some light to my skadis board. So I added a small hole of 12mm wide to the ‘top of the bottom’ 🤔 so you are able to mount a LED-strip underneath the shelf that can run through all these shelfs. I have printed these with normal supports only inside the holes.
