HomePod Mini support for Multiboard

This remix transforms XH_Lab's IKEA Skadis board for compatibility with the Multiboard system.I removed the hole in the center. I don't know what the purpose is.It's slightly thicker to better conceal the wire. I've added a slider to ensure the wire is completely hidden. You will find in the profile, two versions. One with a standard connector for the Multiboard. For the second one, you a connector from David's MultiConnect - generic connector on Printables.The tab is optional. It holds the cable well, but with the version using Multiconnector, the bracket is then more challenging to put on.
