With the S1 and it's various options, you get various tools for both the Xtool S1 and the rotary accessory. I constantly find myself looking for the tools. I fixed this by designing this toolrack. On the back I made two plates with two holes each (deep-engraved to 2mm) to place tiny round magnets with diameter 5mm (available on other cheap sites) in them. This way you can just fix the toolrack to the side of the xtool.
