Off the Grid with Gridfinity! I have modeled some modules that are 100% compatible with Gridfinity but can also be used on their own, connecting together with common 6x3 neodymium magnets. :) To use with Gridfinity, simply print as many adapters as needed (they're 1U) and continue to use your existing Gridfinity system.

My wife received a Keurig for Christmas (despite us being snobbish when it comes to coffee, using our espresso machine, pour over, etc.) and she wanted a nice way to store the cups under the coffee maker's stand. Enter Mod-K! I know there are a ton out there already, but I love designing new things. You'll notice all the holes in the side. Originally, I was only going to make holes for the 6x3 magnets themselves, but figured I could incorporate them into the design. :D
