In order to get successful prints, you have to get the bed leveled. I find myself constantly adjusting the bed especially to compensate the thermal expansion of the heat bed.
This nut lock attachment is designed for PB+ (maybe LC too), giving users the ability to level the print bed easily regardless of glass size and thickness.
Those using corner tabs mods may not be suitable for this mod. I prefer the binder clip method since I can easily install insulation under the heat bed.

Working on a knob for the nut under the heat bed to make adjusting easier.
