K2 Plus bed adjustment knob (prametric)

The heat bed levelling adjustment screws on Creality K2 Plus are pretty small and hard to grip, and very painful to turn, especially if the screws are particularly tight.

This is a knob tool to make the task much easier, without having to damage the factory part.

I recommend 3 wall loops and 20% infill to withstand strength needed against stubborn screws. Print in white material and mark a line with a pencil, so you can easily track half or quarter turns if you need to.

FreeCAD project included.
