I made these as no matter how many times I level my Ender 5 Plus I always had 1 corner where the spring would be loose.
Put these over the screw with the indent facing down then put the spring onto the screw these will then extend the spring's pressure in the corner with slack. The indent keeps the screw centred around the thread.
I include 4 different heights which you can mix and match as needed.
