Remix of CR10 Leveling Knob by Oggie

Edit: 12.02.18
The new version is perfect. Finally.
Just made some and put them on. They fit just right and tight.
I suggest using at least five top layers so the letters are clearer.
Did mine at 0.16, 203C, 62C bed, around 50-55 speed, 20 %infill. Supports are not necessary, but if you get some small stringing i suggest cutting it away with a scalpel which gives nicer edges.
