Z alignment card for Anet A8 & P3Steel

I have been adjusting the height of the Z axis for some time now, with a used credit card. The problem is it, is not rigid enough. I have created a very simple solution. That allows to introduce this aligner, between the screws of the motor and the piece of subjection of the threaded bar. Once both pieces are placed, and with the motors step by step deactivated, you can manually align the height of Z.

Simple solution.
