Friendly magnet
thingiverse
One of my go-to tools in my toolbox is "The Friendly Magnet." It's a breeze to print and put together, requiring only two printed parts and a round neodymium magnet (6mm diameter, 1mm thickness). The part is specifically designed to fit that exact magnet size, but if you're interested in other sizes, just let me know and I'll upload alternative versions. Have fun! Print Settings Notes: I highly recommend printing it in the orientation shown in one of the images.
