Key Chain Magnetic Quick Disconnect

I've been playing too much with magnets and have gotten into magnetic quick disconnect keychains. I made another type that works well for me, but I thought it would be cool to make a system where all the pieces were identical and as such could be swapped with any other piece. With that in mind, I made these magnetic quick disconnect key chains so that you can print as many as you want and, as long as you orient your magnets correctly, each one would fit with any other piece of the same kind. I also just wanted to try out onshape and so I whipped these up in onshape and made a few variations.-------------------------------1st variation: most_annoying.stlThis was the first one I tried. It uses a small dovetail type joint and requires you to slide these together from the side. I quickly found out that this can be kind of annoying when the magnets are inserted, which led to variation 2.2nd variation: normal_flat.stlThis one uses slightly rounded tabs of sort that slot into the next pie
