This is a push fit adapter (very tight) for pieces on the Kingdom Death Monster Plastic Board. A few of the pieces need to be carved out to fit. This uses a 10mmx2mm round magnet. I am planning on using stickers to label the locations on the board. Added another print profile for a slightly smaller insert. Try both and hopefully one works better than the other. Also added a depth gauge insert block.
