Summary

This part is designed to lay on top of an Ikea Not uplight to make a pedestal for the Apple HomePod.

Please refer to that thread for more info on how to mod the Ikea Not uplight (it's very simple).

I've decided to add this part so that the sound from the tweeters would have something to "bounce" on, as it happens when you place the HomePod on a flat surface.

Note: the "reading" version is different and won't work!
