CR-10s leveling wheel for 17.75mm thumb screws

This wheel slides over the thumb screws on the CR-10s. I bought my CR-10s on 11/28/2017. The thumb screws on my machine are 17.65-17.80mm in diameter including the little notches that are on there(see picture).

If you have this size thumb screw, you should be able to give this a go.

I have included an "inward" and "outward" version(see picture). Use either you want, mix and match, get nasty with it. Use the test piece to see if your thumb screw fits the .1mm, .15mm, or .2mm offset version.
