Another version of my magnetic spatula holder https://www.thingiverse.com/thing:3495244
But this time I have used four 12x4 magnets - and they are quite strong!
You can use this when tinkering with your printer and put your metal tools there - spatulas, wrenches, screws, whatever - without fiddling around finding the right holes in a holder - just smack it on the plate and it sticks :)
This holder won't interfere with moving parts of the printer (on my Ender 3 at least)
