bed level helper for wanhao duplicator i3 (and plus)

Two versions of a very basic bed leveler I designed to help with my own printer (an i3 plus)... one with text and the other plain.

Hang both of these at opposite ends of the top x axis rod, and slowly bring Z down until one or both of the levelers almost touch the bed.

Adjust your bed to make sure it's level (essentially, the same vertical distance from the bottom of both levelers). Eyeballing the distance between bed and leveler should be good, in most cases. OR, if there's just not much
