CR10 Bed Leveling Knob

I have a Creality CR-10 and tried several of the available designs for a bed-leveling knob; but none of them fit the way I thought they should or used too much filament.

This was a quick bed leveling-knob I did in Freecad. It is tight to the existing knob, so you need to use a set of plyers or a tack hammer to tap the two together, but once you have them together it works great. It had truly made adjusting the print bed a breeze!
