curved active bed level

thingiverse

I prefer an active level before large prints and i could not find anything that took up the whole perimeter of the bed but also had continual curved surfaces. Active bed level, Set X/Y size to be ~20-30mm smaller than bed size. set z height to layer thickness. default is 180x180x0.2 Monitor and adjust level as it prints. Can help with small errors that don't pop up with square shapes. Uses a very small amount of filament and only takes a few minutes.
